After searching for 1.) How to wire a little relay like this. 2.) How to program one. I have to say this is the best video out there! A lot of them go on and on with various circuit board/technical terms. But this tutorial shows how mpjaonline had it wired up, (thats the main thing that helped me past my hurdle!). This video saved my Halloween Prop! Much thanks!
Bought two on sale , no instructions in the box. After attempting to decipher the vendor`s online nstructions for 5 minutes , not well translated from whatever language they were orginally written I might add.I searched for a video hoping to find one coherent and intelligible, I found this video ... I wish I had found the MPJA webstite from the start ..it will be my go to from now on . THANK YOU FOR MAKING THIS TUTORIAL VIDEO , CONCISE EASY TO FOLLOW AND UNDERSTAND , superb job .
There is one more function: Hold down up or down button (F1 is normal operation, F2 when powered up relay turns on with no countdown time) Stop button turn on and off.
Thank you thank you thank you! I have no experience working with timer relays and as is the case with most small electrical components you can order online the instructions are poorly translated or there are none at all. The available instructions for this particular timer are notoriously challenging to understand and I gave up trying to figure out how to use it months ago. Now after watching your tutorial I can finally use it.
Hello Sir, Thanks for making me understand the connection, means a lot to me, and just because of your demonstration of the connection of this module I am able to complete one of my personal projects, Thanks a lot, god bless you.
From Holland thank you for the tutorial! very easy to understand, very clear video! Thanks a lot!! Greetings from The Netherland and have a nice day. Peter
Thanks for this tutorial! It was very clear and it helped me understand how to use this relay. The written instructions that come with the board are super unclear, so this video was quite helpful.
really appreciate this video.. the broken translated instructions that came with it was terrible..🤣 I sussed some features out by playing around but your video helps so much. 👍
Depends on your sensor if it has an adjustable set point (on-off) and a transistor output to act like the switch I used. Plus a separate power source for the delay timer 6-30Vdc. Thank You
Thank you very much for this awesome video. Just received this in the mail, but had no idea how to program it with no instructions. If you ever do another one, it'd be very helpful to hook something up to the NC or NO side, to demonstrate the on/off function, like a light or fan or something.
You do have to have an external trigger voltage. Simply using a switch doesn't work. When using USB power there's a 3.2vdc across the power terminals but it's not enough to use as trigger voltage. As such I think USB power is only really useful if you are using P3-1 or 3-2.
nice! I have an old car (brasilian pickup Chevrolet Montana, same as Opel Corsa C) and setting ignition on position 1 doesn't turn the ACC on (it turns on only when holding the key pressed in) for now the ACC IN signal for my Android headunit is coming from the ignition 2 position, so it only works when my dash is on, whith all the engine systems, with engine running or not I belive I can use this module setted on program 4 to allow my headunit to keep working for 30 minutes after I turn ignition off also I can cut power for the module when locking the car thanks for your video!
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 dialer. 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.
Awesome, thanks! All of the instructions I have seen to date on these are so poorly written as to be unintelligable! THanks for the video, makes using one of these a breeze!
This is really good. But I got some questions. Can you use a 9 volt battery or other batteries to power it? Do you have any videos on the wiring? I am mildly confused with the ground cable. Does it need it? I want to make sure I wire it with the trigger and the battery and everything. I'm kinda new to electronics and I just built very simple things.
Thanks for your efforts and sharing 👍🇬🇧 I was hoping to see this switch polarity also, with option to set voltage and amperage. If you know of a device please let me know
Thanks for the video, helped me understand the trigger function. Can anyone recommend a 2-channel version of this? I want to power 2 circuits sequentially, then have an off cycle. Currently using 2 of these with the first's NC triggering the 2nd when the first closes, but thats a lot of wires =/
The "standby" current requirement is 20mA, and the "Relay Energized" requirement is 60mA per the datasheet on mpjaonline's website. So a typical "9Volt" battery wouldn't last long. Even a high-capacity brand new fully charged lithium-ion "9V" form-factor battery only has about 800mAh capacity. So if the board was in "standby" ALL the time, the lithium battery would last about 800mAh/20mA=40 hours...less than 2 days. (note: a lithium "9V" battery is actually a maximum of 8.4Volts and can be used down to about 6.0V)
Thank you very much for this video. I am trying to use programming mode P3.2 (OFF and ON in a cycle, without trigger). However, it always starts in OFF mode. I need it to start ON, then OFF (I am using the relay with a separate timer that has a minimum period of one minute. I need the relay to limit this to, say, 10 seconds. This way, I can set the main timer to power up the relay, and the relay stays on for 10 secs, then shuts off). As it is, I get a mode flashing for a few secs on power-up, then it starts the loop in OFF. The loop works OK, but all this delay at startup is frustrating. Any way to set P3.2 to start in the ON position, no off? There are no instructions. Thanks!
Thank you sir for informative video, With this triggered timing board i want to make a project for home, can you please guide me? and sorry for bad grammar English, Actually i want to make a timer circuit with my doorbell at home when someone outside trigger the bell button of my home bell then the 50watt socket system turn on for specific time like (120 seconds etc) in 50watt socket system i will include 1 x door security camera 1 x 20w small LED/LCD monitor for Camera display 1 x Night LED light for outdoor (with lowlight sensor) if someone ring bell at night (Note: my door bell is like bird singing voice, as long it keep ringing as long the bell button is pressed) (Another thing: it will be more great for me if bell bell is repeatedly pressed by any person then there will no affect on this timer board, and the electricity of door bell should be separate if possible..
I have a question, when using the P31, infinite loop with time on and time off, is there any posibility to override that, one time off and leave a bit longer on and then continue the normal loop? I saw the different options but I didn't see any that does exactly that. Thanks so much for your help and your great videos!!
I have problems with this board regarding debouncing of the pushbutton. Did you debouced the switch? I'm using a wall push button to start a fan in mode 1.3 and I have double triggering sometimes.
Hello! I have this unit and your video has been extremely helpful however I'm finding that program P2 delays the relay as expected and then turns it on (LED lights up) HOWEVER if you press the trigger while the relay is on, the program starts over. In your example, the trigger starts the program but then is ignored if it is triggered again while the relay is open? I also found that my counter is counting UP, not DOWN like yours. Thoughts?
I bought the timer a few months ago and finally I decided to use it, but it doesn't work properly. If I set the times from 1 to 10 minutes it's all right, over 10 minutes (any value I set) stops at 1 minute and 5/6 seconds. And even with the program in seconds has some problems.
Great video. I wonder if NC is closed when timer is at "Off" cycle. As an example, can I run one motor when timer is "On" and run another motor when timer is "Off"?
I'm looking to buy this with the black relay. They also do a double relay vs. I would like to know, if i get the 24V dc input version. Can i wire 24V dc in parallel to the trigger port. Does it have a memory? In other worlds i would like to power it up and it automatically counts down the pre-programmed time till the relay switches? I have a large DC amplified speaker, i wish to add speaker delay protection in series with one of the speaker wires, one unit for treble and one for bass. I would use the double vs. but they only come with the 10A relay.
I just received mine. Hooked it up, without a load, the timer counts down and the relay clicks on and off as it should. After load is connected, com to power+ and NO to the load, the timer instantly stops after triggering. As far as I can tell with the probe on resistance buzz, the relay never closes? Hope someone can help!
I'm on P-3.2 mode with Open 10s, close 3s and loop = 3. what my problem is, like at 10:40 it does not energize the relay, and it waits until end of P-3.2 blink to energize the relay. there's about 2 sec delay. how can i program this to overcome the issue ?
The problem I have with the Programmable triggered timing board 35238 MP is when trigging on and of it will stop working over time I had to replace it 3 times / using a small scooter battery 12 v / do in need to add a fuse ? . or is there one on the board,?

Could not have done i without your video! Thank you.
This is perfect , 3.2 is the program I was looking for 👍😁
Thanks for the video, best explaining video of this module I've seen so far
You are wonderful! I truly appreciate your complete explanation and also showing how you wired the darned thing!!! Thank you so much!!!
Thank you so much for this. It's a better unit than I thought I bought thanks to you.
thank you! very helpful video. I will definitely be buying some of these from MPJA.

Great tutorial. Thanks! The instructions in the chinese pages for this device are all but unintelligible and were driving me crazy.
Great simple video in real language - can you tell me why my unit counts up from zero rather than down from presets.

can this be hooked up with a motion sensor and a nine volt battery supply?
Yes it will work with a 9V battery but depending on the current draw of the PIR and how often it is triggered the battery would last less then a day.
@@mpjaonline alright, what does PIR mean?

Yes the relay output has a normally open and a normally closed contact.
I'm assuming it is a "standard" break-before-make relay? Not trying to be a pain, just being sure on the spec.
Thank you for the video. Is there a way to have it start the relay when the switch goes from closed to open?
This video was extremely helpful. However my timer is going up instead of down and i want it to go down. Help if you can. Thanks
