hey Ray, hitting the stop button doesnt move the seconds to miliseconds in the time selection screen. I thought it might be the button but i shorted the button by hand and it still didnt work. Is my process correct? Set the p1.1, hit the "set" button OP Flashes on the screen, and it switches to the 000. screen. I hit the STOP Button expecting it to switch to 00.0 but nothing happens.
Great demonstration, thanks. I'm using one for an alarm system where I use a trip wire attached to a pull pin that operates a micro switch to send a 12 volt signal to trigger the board and sending an operating voltage to sirens, lights and GSM dialler. Now, here's the thing, It works most times but occasionally does not and I have a theory that the time length of the signal, on occasions, may not be long enough. A trip event pulls the pin out super quick and, once pulled, the micro switch instantly returns to its normally open state. I suspect that if the micro switch closed circuit condition is only in the order of milliseconds, it may not satisfy the boards signal parameters. What do you think? Ps. I have just modified the micro switch assembly to remain closed circuit after activating, until reset, so I am testing a few more times to check my theory out.
@@raykd2ibp198 Yes, using the N.O. connections of a micro switch with a roller arm that closes the circuit when lifted by a ramp on the withdrawing pin. When the trip wire is walked through, the pin pulls through the micro switch in milliseconds.
@@SuperRealityKid Not to read judgemental.. however, this reads like a contraption. You might want to simplify the trigger. Try circumventing the whole switch setup and see if the board goes through the programed sequence .
@@raykd2ibp198 🤣It's actually super simple in construction. The "pin" or 4" long 3/8" stainless rod is inserted into a lose fitting tube with a slot along its length on the top. The rod has a high spot that is guided by the slot and operates the micro switch when it's pulled out of the tube by the trip wire. Mechanically it works flawlessly every time but I will try operating the microswitch manually without using the pin.
Good day, I have found some things are not consistent with these boards. This is just an introduction to this board. You may need to play around a bit.
Hi Ray, Great instructions, I am unable to programme so that an alarm will trigger for 3 seconds and then switch off each time it is triggered.. I cannot locate P1 on my controller. Trigger is a pressure switch, alarm is a siren. Seemed simple to me but having heaps of trouble getting it to work. best regards Glen
Hi got a few questions please. What happens if the signal input is constant and doesn’t switch off Do both sides of the board need to be grounded and can they be grounded to the same point ? Ho to you change from NO and NC please
Hi Saroo, 1) Depends on how many cycles you program the bord to run. I believe to reset the trigger, the signal has to drop to low. 2) Same power source for both sides? I like to keep both sides isolated. 3) Its how you wire the right side of the board. Common remains the same. NO/NC is a wiring option.
@@raykd2ibp198 1) I just want the board to run once cycle when it's gets a signal trigger then do nothing until signal goes off and back on. 2) no sorry I meant same/common ground for all grounds on the board Currently I have my input signal which is 12v and stays on until it loses power from another switched relay. On the right of the board I have 12v permanent and ground (which shared with my load ground) then my output + to my unit/load which is already grounded separate. Would this set up work on mode p1.1 to trigger power for 10 seconds to my unit/load then go off and not provide power again to my unit/load on output + until the signal trigger is lost and re triggered please Thank you for your reply really appreciate it 🙏
Hi Ray, thanks very much for the video :) Do you know if this board/or another board will hold the contacts open for a second or two when mains power is cut. i.e. I'm trying to come up with a solution that will delay the contacts opening when first provided with power, leave the contacts open until power is cut, at which point the contacts will continue to stay open for a second or two and then close
Hi Damian, If I understand the question correctly... You want both delay on "make" when power is applied. And a delay on "break" when power is removed?
Damian, I don't believe this board can run two modes concurrently. Although, I believe this board will support both functions independently. Look thru the attached modes of operation list in the comment section. What kind of voltage are you working with?
Would this all work the same if it were powered by 9v? Also would resistance in the load change amything? I'm using 9v and my load is just a globe. When the globe isn't attached it works fine according to the indicator light but the the circuit it closed, the indicator flashes for a split second then goes out regardless of programming
Hey Chris. Yes that's the trigger. It's all in the programing. If you get stuck give me an idea regarding proposed sequence of operation. You don't need to get detailed. whatever is being turned on or of we can just call the load.
@@raykd2ibp198 Thanks. The project I'm trying to build is fairly simple. Power source 9v. 1. Trigger is a momentary switch that tells the module to close the circuit to the load and provide it power. 2a. If the momentary switch is released, delay off timer ends immediately and the circuit opens with no more power to the load. 2b. If the momentary switch remains depressed, the circuit stays closed until the delay off timer ends and opens the circuit. The issue I keep finding is that the modules all respond to the trigger, start the timer, but I can't interrupt the process if a momentary switch is released. Do you know anyway to program them to make the above happen? Thanks again for your channel.
I may not be using Delay On and Delay Off correctly. The ultimate goal of the module is to prevent continuous load beyond a set number of seconds, but have the user have the ability to stop the load the moment they release the momentary switch.
I also have an 12volt cirquit time board, but I don't understand it. I have an weight trigger micro switch, a micro water pump and the cirquit board. What I want is put a glass on the micro switch then the cirquit board goes on and stays on for like 3/4sec and turn on the pump and turn it off after 3/4sec. How can I do that?
Good morning :) I hope this helps you to get to where you are going. Please let me know if you get stuck. 73. -Ray th-cam.com/video/YlmAey_HTJk/w-d-xo.html
Hi can the trigger only be momentary or can it have 12v constantly and start the timer when the trigger is removed? I want to use this in my car to power a radio. Like a failsafe that if I forget to turn the radio off it will time out after say an hour using the ignition 12v as the trigger
@@raykd2ibp198 Hi Ray, Thanks for the reply. Its currently plugged into the 12v cigarette lighter socket but this switches off with the ignition. I would like to be able to use it without the ignition on or engine running. My idea is to wire it from the battery but have a failsafe so I dont leave it turned on by mistake. Being a canbus car its more hassle than its worth trying to find switched power that is on with the ignition off but goes off when i leave the car. This seemed like a good option.
Hey mark. Yes you can set the board to count down and open contact after trigger closes contact. See operation P3.1 attached in the comment section. you would just install a momentary push button type switch to trigger the board.

So what I did was getting the timer and a relay. So far so good. I give the VIN (-/+) a 12V juice, I took a momentary switch for the trigger and gave the trigger juice from the VIN current. I connected the relay to the output of the timer and also soldered a 1k resistor and a led to see when the relay is open. I turn everything on, leave the progra on P1.1, set timer in 5 seconds, I test the STOP button, program it to OFF, press the trigger nothing happens - expected. I click STOP again, screen says "ON", the LED turns on, I'm like "wtf are you doing...?". I pull the trigger and as it counts down from 5 seconds to 0 the LED turns off and as soon as it reaches zero, what do you know, the LED turns on again and I'm left speechless!
Good day sir. (Name please) K, What exactly are you looking to achieve in terms of sequence of operation after trigger? Time contact is closed, or open etc. Also, the board itself is like a solid state relay. SPST. Unless you are looking to drive a higher current than the transistors can handle. Or, you need to control more than one pole at one time, there is really no need to add another relay. I believe it's best to keep circuits as simple as possible. The less components used to achieve the final goal the better. More components = less stability, higher maintenance, and greater parasitic load.

@@raykd2ibp198 🤣It's actually super simple in construction. The "pin" or 4" long 3/8" stainless rod is inserted into a lose fitting tube with a slot along its length on the top. The rod has a high spot that is guided by the slot and operates the micro switch when it's pulled out of the tube by the trip wire. Mechanically it works flawlessly every time but I will try operating the microswitch manually without using the pin.
@Super Reality Kid k. How's about a video? Get yourself out here brother!
Have noticed these arrive with different programming requirements. Is this common with these kinds of timers even though they look the same?
Good day, I have found some things are not consistent with these boards. This is just an introduction to this board. You may need to play around a bit.
Hi Ray, Great instructions, I am unable to programme so that an alarm will trigger for 3 seconds and then switch off each time it is triggered.. I cannot locate P1 on my controller. Trigger is a pressure switch, alarm is a siren. Seemed simple to me but having heaps of trouble getting it to work. best regards Glen
Good day. Can you send me a pick of your board? See if you can get the numbers in it. (Version)

@@Ezivnelg I'm sorry I didn't get the email.
Hi got a few questions please. What happens if the signal input is constant and doesn’t switch off
Do both sides of the board need to be grounded and can they be grounded to the same point ?
Ho to you change from NO and NC please
Hi Saroo,
1) Depends on how many cycles you program the bord to run. I believe to reset the trigger, the signal has to drop to low.
2) Same power source for both sides? I like to keep both sides isolated.
3) Its how you wire the right side of the board. Common remains the same. NO/NC is a wiring option.
@@raykd2ibp198 1) I just want the board to run once cycle when it's gets a signal trigger then do nothing until signal goes off and back on.
2) no sorry I meant same/common ground for all grounds on the board
Currently I have my input signal which is 12v and stays on until it loses power from another switched relay.
On the right of the board I have 12v permanent and ground (which shared with my load ground) then my output + to my unit/load which is already grounded separate.
Would this set up work on mode p1.1 to trigger power for 10 seconds to my unit/load then go off and not provide power again to my unit/load on output + until the signal trigger is lost and re triggered please
Thank you for your reply really appreciate it 🙏
Hi Ray, thanks very much for the video :)
Do you know if this board/or another board will hold the contacts open for a second or two when mains power is cut.
i.e. I'm trying to come up with a solution that will delay the contacts opening when first provided with power, leave the contacts open until power is cut, at which point the contacts will continue to stay open for a second or two and then close
Hi Damian, If I understand the question correctly... You want both delay on "make" when power is applied. And a delay on "break" when power is removed?
@@raykd2ibp198 Hi Ray, yes - that's correct
Damian, I don't believe this board can run two modes concurrently. Although, I believe this board will support both functions independently.
Look thru the attached modes of operation list in the comment section.
What kind of voltage are you working with?
Would this all work the same if it were powered by 9v? Also would resistance in the load change amything? I'm using 9v and my load is just a globe. When the globe isn't attached it works fine according to the indicator light but the the circuit it closed, the indicator flashes for a split second then goes out regardless of programming
9v question answered i see but the rest I'm still wondering
What is the globe? Is there a light in it?
@@raykd2ibp198 a low resistance globe. I think I've figured out that i need higher resistance or it just shuts off. Thankyou for your reply though
Is there a way to make the board start and stop the timer if a momentary switch is pressed then released?
Hey Chris. Yes that's the trigger. It's all in the programing. If you get stuck give me an idea regarding proposed sequence of operation. You don't need to get detailed. whatever is being turned on or of we can just call the load.
@@raykd2ibp198 Thanks. The project I'm trying to build is fairly simple.
Power source 9v.
1. Trigger is a momentary switch that tells the module to close the circuit to the load and provide it power.
2a. If the momentary switch is released, delay off timer ends immediately and the circuit opens with no more power to the load.
2b. If the momentary switch remains depressed, the circuit stays closed until the delay off timer ends and opens the circuit.
The issue I keep finding is that the modules all respond to the trigger, start the timer, but I can't interrupt the process if a momentary switch is released. Do you know anyway to program them to make the above happen?
Thanks again for your channel.
I may not be using Delay On and Delay Off correctly. The ultimate goal of the module is to prevent continuous load beyond a set number of seconds, but have the user have the ability to stop the load the moment they release the momentary switch.
OK, What if you have a NC momentary switch to kill power to the board as a reset?
@@raykd2ibp198 Thanks for the suggestion. I’ll look at options.
I also have an 12volt cirquit time board, but I don't understand it.
I have an weight trigger micro switch, a micro water pump and the cirquit board.
What I want is put a glass on the micro switch then the cirquit board goes on and stays on for like 3/4sec and turn on the pump and turn it off after 3/4sec.
How can I do that?
It's like a drinks tap when you put your glass on it and shut off after a few seconds with pumping drinks in your glass
Good morning :) I hope this helps you to get to where you are going. Please let me know if you get stuck. 73. -Ray

Hi can the trigger only be momentary or can it have 12v constantly and start the timer when the trigger is removed? I want to use this in my car to power a radio. Like a failsafe that if I forget to turn the radio off it will time out after say an hour using the ignition 12v as the trigger
Hi Mark. I'm not sure. Wouldn't it be easier to have the main power to the radio wired into the vehicle's ignition switch circuit? Key off = No power.
@@raykd2ibp198 Hi Ray, Thanks for the reply. Its currently plugged into the 12v cigarette lighter socket but this switches off with the ignition. I would like to be able to use it without the ignition on or engine running. My idea is to wire it from the battery but have a failsafe so I dont leave it turned on by mistake. Being a canbus car its more hassle than its worth trying to find switched power that is on with the ignition off but goes off when i leave the car. This seemed like a good option.
Hey mark. Yes you can set the board to count down and open contact after trigger closes contact. See operation P3.1 attached in the comment section. you would just install a momentary push button type switch to trigger the board.
Mode selection screen: Long press the "SET" key to enter, after setting is completed, long press the "SET" key to exit back to the main screen.
Operating mode:
P1: trigger signal, the relay is on "OP" time, and then disconnect; in the "OP" time, as follows:
P1.1: signal is triggered again, invalid
.
P1.2: signal is triggered again, the clock is reset
.
P1.3: Signal trigger again, relay off, stop the clock.
P-2: trigger signal, the relay off "CL" of time, the relay on "OP" time, and then disconnect relay.
P3.1: trigger signal, the relay is turned on after the "OP" time, the relay off "CL" time, then the operation cycle, if the trigger signal period, the relay off, stop the clock; the number of cycles ( "LOP ") can be set.
P3.2: without triggering signal, the relay is on "OP" time, the relay off "CL" time, and has been cycling; frequency ( "LOP") cycle can be set;
P-4: signal holding function. If there is a trigger signal timing is cleared, the relay remains on; when the signal disappears, after the timing "OP" time, the relay is; if another signal during timing, timing is cleared;
After setting the mode selection screen parameter value by a short press "STOP" button to select the time range;
XXX. decimal point in the unit place, time range: 1 second to 999 seconds.
X decimal point in decade place, Timing range: 0.1 seconds to 99.9 seconds
X. X. decimal full brightness, Timing range: 1 minute to 999 minutes.
For example, you want to set "OP" is 3.2 seconds, then move the decimal point to decade place, the digital display 03.2
Parameter description: "OP" - conduction time, "CL" - off time, "LOP" - the number of cycles (1-999 times, "---" represents infinite loop).

Timing range
0.1 seconds (min) to 999 minutes (max) continuously adjustable
How to choose the time range?
These parameters are independent of each other, but is shared by each mode. For example, in P1.1 mode, set the on-time "OP" is 5 seconds, if you switch to P1.2 mode, it's "OP" will be 5 seconds too.
In the main interface (display 000), short press "SET" button will display "OP" ( "CL", "LOP") and the corresponding time XXX;
Some parameters only mode "OP" (such as the mode P1.1, P1.2, P1.3), short press the "SET" key to display only the "OP" and the corresponding time;
Some models have parameters "OP", "CL", "LOP" (such as the mode P3.1, P3.2), short press "SET" button will display "OP" and the corresponding time, "CL" and the corresponding time, "LOP" and the corresponding number of times;
In the main interface by short press "SET" key to see information about the parameters of the current mode, very convenient!
How to set parameters?
First, read the instructions to determine the required operating mode.
The module is powered up, the display at the current work mode (P1.1 default mode), then enter the main interface; press "SET" button for 2 seconds after release to enter mode selection interface; a short time by pressing "UP", "DOWN" key to select the mode (P1.1 ~ P-4).
Select the mode (such as P3.2), short press the "SET" button, then the parameter to be set flashes ( "OP" on-time, "CL" off time, "LOP" cycles ( "---" represents infinite loop)), by "UP", "DOWN" keys to adjust the parameter value, support long press (rapid increase or decrease) and short press (increase or decrease one unit); then short press the "STOP" key to select the decimal point position, select the time range (0.1 seconds to 999 minutes); short press the "sET" button to set the next parameters of the current mode of procedure is as above.
After the parameters are set, long press "SET" button for 2 seconds then release, the name of the current mode will flash once, and then return to the main screen, set the parameters of success!
The main interface: In the relay does not work status display "000" (no decimal point), with a decimal point under relay state.
Mode selection screen: Long press the "SET" key to enter, after setting is completed, long press the "SET" key to exit back to the main screen.
"STOP" button extensions:
Relays enable mode:
ON: Relay allows conduction in the "OP" on-time;
OFF: relay prohibit conduction is always closed;
In the main interface, short press the "STOP" button to switch between ON and OFF, the current in which the state will flash, and then return to the main screen. (This feature is an emergency stop function, click off the relay)
Sleep mode:
"C-P" Sleep mode: five minutes without any operation, the digital display automatically turns off, the program running as usual;
"O-d" normal mode: digital display always open;
Press the "STOP" button for two seconds and then release to switch "C-P" and "O-d" state, in which the current state of flashes and then return to the main screen.

@@raykd2ibp198 no it's ok and thank you for your time. so I need to have a specific low signal going through a wire. I wanted to interrupt the wire and put a relay which would open and close again for a specific amount of time, only once when the timer circuit would be triggered. So what I did was getting the timer and a relay. So far so good. I give the VIN (-/+) a 12V juice, I took a momentary switch for the trigger and gave the trigger juice from the VIN current. I connected the relay to the output of the timer and also soldered a 1k resistor and a led to see when the relay is open. I turn everything on, leave the progra on P1.1, set timer in 5 seconds, I test the STOP button, program it to OFF, press the trigger nothing happens - expected. I click STOP again, screen says "ON", the LED turns on, I'm like "wtf are you doing...?". I pull the trigger and as it counts down from 5 seconds to 0 the LED turns off and as soon as it reaches zero, what do you know, the LED turns on again and I'm left speechless!
Good day sir. (Name please) K, What exactly are you looking to achieve in terms of sequence of operation after trigger? Time contact is closed, or open etc.
Also, the board itself is like a solid state relay. SPST. Unless you are looking to drive a higher current than the transistors can handle. Or, you need to control more than one pole at one time, there is really no need to add another relay.
I believe it's best to keep circuits as simple as possible. The less components used to achieve the final goal the better. More components = less stability, higher maintenance, and greater parasitic load.

@@raykd2ibp198 yup using not to control a starter relay
@@niius7663 hello friend. I have same relay using it as on off relay to control my heating system. In this video I understood how to connect the trigger. It needs power. The relay works 4-6 hours every day.
hello, how to connect an IR module as a trigger? Thank you for the video
Can you show me the IR module?
@@raykd2ibp198 Here's the link,thank you www.ebay.com/itm/Smart-Car-Obstacle-Avoidance-Infrared-Sensor-Module-Reflective-Photoelectric/191848903842?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649
If the module sends out +5 volts dc to the trigger in theory, yes this is doable. if you want to share in greater detail what it is you are trying to accomplish in terms of sequence of operation... I maybe be able help you out better. The IR board is limited distance wise.
@@raykd2ibp198 Ok, I'm trying to make an automatic hand sanitizer dispenser but with the IR module, if you don't take your hands off, you're always putting the sanitizer on, so with the XY-J04 CMOS maybe I can stop it after a few seconds, say 2 or 3 seconds.
I did this:

But I want to do this and use the XY-J04 instead of the XY-J02:

Thank you
Ok, eliminate the transistor, and resistor from the cricut. Use the +5 volts you were driving the transistor with to now trigger the board.
Use the pump supply voltage to feed the input voltage on the timer board. The load side on the timing board now drives the pump.
The trigger could also be the peizo speaker on a $1 watch or clock.
Ok never tried it. You have?
@@raykd2ibp198 No, but I've seen it used to trigger a relay on VERY similar circuits.

Hi Boddu. How can I help?
I use 12v it's working fine
I want to use 24v and it's broken with a little explosion sound
It's a lie when it say 3-30v
Ha! Goood morning Rakasiwiii. Care to elaborate regarding what you have going on? These boards aren't built for quality in my opinion. However, I think they're great for prototyping ideas. The upside....you can afford to blow up a bunch of them without a teardrop. Even if we blow them up due to our own error. I do it all the time! Keep the learning fun! 73,

-I need 12v with time delay to alternate between on and off for my led strip (lets say 1h off and 1h on)
-i need 24v with timer to alternate on off for ultrasonic mist maker (lets say 5m on and 20m off)
So I bought 4 of this product becouse it say it can withstand 30v.
I try to built the mist maker (with source 24v) but it didn't works so I test my other relay with 12v source and it works just fine. I got curious and change the source with 24v and snap the 7segment die and the relay indicator stay on. So I broke 2 of this device 😁 and my conclusion this thing can't withstand 24v
I want to try to give input of 12v and boost it's output to 24v with buck converter but afraid it won't work or broke my other components, if u have any advice pls tell me
So Tomorrow I want to try it with 5v input(may be it's safer with 5v?) and just connect it's output into relay to drive 24v my mist maker wanted
Nb: english is not my native so forgive my broken english
And cheers
@@CharDhue You're doing fine.
Me mindful of how much current you are pushing thru the circuit. RMS and inrush current are factors.
Make sure you are not energizing a dead short too.
You can also use the final circuit to drive a a larger switch, big enough to power up a city grid if you needed.
@@raykd2ibp198 rofl, I'll try my best to power up my whole city
Wish me luck 🤞
