Wow, wow, wow. Any questions people would have you have answered. Excellent video, thank you good sir !
He didn't show the most important part which is how to connect it.....
Good and thorough explanation including safety issues. 👍👍 ✔️✔️
I was frustrated with potentiometer. Adjusting it tiny bit by bit...I am happy now to know i need to turn it 10 + times:D thank you!
You're welcome!
Hi, do u use an extra suply for the lamp or the delay transfor mthe 12v in 230v by the relay?
Thanks .
It means capacitor tolerance
may effect time accuracy for repeat cycle by 10%.
#i.e. If set for 6 second repeat accuracy may very from 5.4 sec to 6.6secod may I right.
#One more thing current(ma) consumption for 12 volts d.c power supply to operate relay& circuit.
Huge thx. I'm a novice so this really helped! 🙏
You are very welcome.
I have just changed the variable resister for 5meg ohm and the big capacitor from 100 to 1000uf can now get well over half an hour time which is what I needed.
good trick
Can we combine it with wireless relay switch remote 433 mhz as a trigger?
Thank you for explaining how to connect it, I will use it for my car amplifier. In the winter I don't want it to turn on and draw power until my car is started
Glad I could help
Excellent explanation, thank you!
you are welcome. here if you want to change the time or add a reset button th-cam.com/video/LDLPUpU64J4/w-d-xo.html
Thank you sir, your video helped me lot...
You are welcome
Thanks for the video. One question: I have 24DC source, is there a way to still use this module or is there 24V version of this module as well? Thank you :)
Hi, you may find the 14V version but I have seen 12V. But I have tones of other amazing timer . Just search for the word "timer". Here is how search for a particular video in a Channel th-cam.com/video/OhkUceBWcHs/w-d-xo.html
Sir 1 sec to 10 min ? any link for buy ?
Well explained, thanks.
You are welcome.
Thanks for the video, very clear!
You are welcome.
Very good video kindly I ask you if can modifying to be power on instead power off best regards
It already has it. Just connect your load differently. Relay has three wires. Keep the the middle wire and mic the other wire to other terminal.
Hey, I want to take input in this timer module using a sensor. Is it possible and if so how should I do it. Basically I want to make a delay circuit for automatic hand sanitizer dispenser using IR sensor.
Hey, You can use infrared sensor to detect hand using this video th-cam.com/video/T3Li128GBlM/w-d-xo.html and the output of the sensor can be connected to this to trigger it. good luck
would something like this be apple to operate a dpdt relay that reverses polarity on a motor and without big voltage drain when the car is off? I suspect a capacitor would be involved so that when the car coes off, the relay reverses polarity on the motor to operate for 2 seconds
The car battery voltage go up to 14V and I am not sure this muddle can withstand that violtage. I would suggest using a buck boost conveyer so it always outputs 12 even if the input is 9V when you start the car.
Can this timer module be used for less than 1 second. Eg. 0.5 seconds? That means turn on for 0.5 seconds then turn off. For spot welding 18650 battery application.
It has a potentiometer and try it. I am not sure.
I want to add LED turn signals to my ebike, and my first thought was to use this type of timer to control the flashing rate of the LEDs... but most of the videos I saw on turn signals are using relays. Am I overcomplicating things by using such a timer?
this module is not that purpose. You need different module that has loop or better use Arduino. Learn Arduino in 30 Minutes (video): robojax.com/L/?id=135 where you can do anything you want.
Could I use this for a door bell disconnect ? I have an automatic door bell and want to delay it 10 sec in between each ring.
this can be used when the bell button is pressed, this too just turn OFF the bell after the set time. Yes it can be used.
The input coil voltage is nominal rated on 12VDC, but whats the maximum input voltage the coil can handle? is this the same as the maximum output voltage?
have tested it with 12V. Search for the model of the relay and see the datasheet. I advise against it any voltage 5% greater than rated voltage. but read the datasheet.
Do you have the schematics?
Is it possible to make a trigger push switch connection in this module. Can a IR sensor be connected because only positive and negative terminal connection is seen.
it doesn't have any trigger option. May be this would better option th-cam.com/video/ZRAaTRKRmh0/w-d-xo.html or see them all th-cam.com/users/robojaxTVsearch?query=timer
Hi Robojax, i need very important information. Sensitivity of this circuit. If you flicker the DC (9v/12v) for few say haf a second (200-500ms) does relay detach?
you should not connect it to 9V. it is 12V rated. Yes voltage will affect it. see how to add reset push button and increase the time th-cam.com/video/LDLPUpU64J4/w-d-xo.html
thanks for the video, is this timer can set to 2-3 hrs interval ?
You are welcome. Please watch the video. it has been mentioned at 00:08 and 00:17. You might need this th-cam.com/video/dtc4UL2bEs4/w-d-xo.html
Very good demo. Can the timer be initiated with just a single short press push of a button switch, or does the control power need to remain applied during the timer period.?
I have a video where showing how to increase the time, add a push button. link is description or search my channel for keyword "hack"
control power needs to remain. I thought the capacitor would allow a short burst of power then discharge over the delay period but it doesn't. Shame
Thanks mate for this video! Really helped me to design my device!!
You are welcome.
Can this start a timer from a pulse or does it have to have constant power. I need a pulse to turn on lights for a short time.
May be if you look at this video , it will work for you th-cam.com/video/LDLPUpU64J4/w-d-xo.html
Nice video.i have a adjustable timer similar to this but no real directions for it.just a very vague diagram.i was wondering if you could tell me how to wire it if I sent you a picture of the diagram I have?
this video is made so you know to connect it (wire it). Isn't it?
@@robojax well I have a different type of board but not very good directions as was wondering if I sent you a picture and the diagram I have if you could tell me how it works coming from the relay end.
hey and thank for th vedio
I want the counter start to count when I relase my finger or cut the power?
I mean i want it delay off..
when i press power the light turn on and it countinus lighting until I cut power off then the light turn off after 5second
You can't do much different with this. Here are my videos where you can use Arduino to do anything or use different timers here th-cam.com/users/robojaxTVsearch?query=timer
@@robojax thanks my friend but I dont want to use Arduio with that. because I want more the one . I want to use it in deffernt places so Arduino doesnt help me
@@robojax my friend I want as this circut in this video

Did you ever find what you are looking for. I am looking for a 1 second time off also. I am having no luck. If you have found it please help me.
How about A 12V source to a 12v load. I need a loop that is: 12v water pump runs for 4 minutes, the shuts off for 45 minutes, then loops indefinitely. Thanks, Chuck
Perhaps you need this module th-cam.com/video/81XzLwt3dqo/w-d-xo.html
I have a couple of this and i need to make a light that fades on and fades off until the power source is depleted, how would you wire it?
perhaps you did not watch it. this is just switch which turns ON or OFF. there is no fading.
@@robojax Lets ignore the fading, just an ON for 10 secs OFF for 10 secs in the light, how would you wire it using a couple of theese or just one?
connect them in parallel meaning + of all of them to + and GND (or -) of all of them together to power up. Then connect each load (LED or light ) to each module as shown in video.
Nice video, i am looking to power off a light after 10 sec. However, i don't want it to power back on automatically even though i have power still coming in. My scenario is, power comes on then delay power off (10 sec) then sit there. I turn off power, turn on, then again power off after 10 sec. Would this device allow that?
Here is Arduino based time th-cam.com/video/6DGQhQgr7Ak/w-d-xo.html this module you are using can't do much as it is made like that.
What is the accuracy of time
once it set .
I. E . suppose if pot. set for 6 sec. what is repeat accuracy.
If timer run for continuous
operation. With rest time of 5 to 2o second.
Also where it available & price.
it is running with simple capacitor with 10% tolerance so you should not expect exact time. You can get it from www.ebay.ca/itm/201655542608
Hi, iv just purchased 2 of these but the 12v out is only on the 2 inner legs of the relay, and it will only output to those 2 legs once the relay has energised, i presume there faulty, cheers.
Hi, yes. to use it as switch, you just need to connect two wires. Here is a hack for this to increase the time th-cam.com/video/LDLPUpU64J4/w-d-xo.html
@@robojax Mine seems to be working in reverse, its instantly energised and the timer de-energises after say 10 seconds, do they do 2 versions of this, after the set time of say 10 seconds there is no 12v output, thanks.
So, instead of 230v application, can we use it with 12v for car lights?
It is a relay. Relay is a switch and I mentioned that you can connect AC or DC load. And car battery is DC. So yes
is it possible to use this to turn off a pc. i just need the timer to set for 1second or less since pc on/off switch is momentary. this will be connected to a relay which will trigger its 12v power. thanks
basically, what i need is a single pulse signal. like it will turn on for 1second or less then turn off. is that doable with this circuit?
I don't know how you are going to use it. As demonstrated at 05:30 when you power it up, it waits for the set time and then connect or disconnect. But i can be set to 1 second.
hi i have a project where i need to convert pulse 12v DC to constant 12vDC will this relay work. Im a very begginer in electronic components. But i understand i need something to store the pulse dc on one side and release it in one constant flow on the other side, is that correct?
This is a switch that can turn ON based on the settings. (or turn OFF if you connected differently)
For constant voltage u need dc-dc buck converter
@@atwalcheapenergy3918 how does that work? 🤔
This circuit can usable in car dome light?
this is just a switch and you can use it for any load of 10A. See the video for explanation. if you want to change the time or add a rest push button on this module then see this video th-cam.com/video/LDLPUpU64J4/w-d-xo.html
How to connect this circuit with car rooflight and get fade on off
is it possible connect potentiometer in place of preset
yes, just remove the existing potentiometer and connect yours.
I bought a similar looking device to achieve this exact effect, that is, the delay. However my module does the opposite. It commutes the relay when you power it on and goes off after the time set on tje potentiometer. Can I hack it to achieve the effect I need?
Just change the wires. keep the middle wire for the relay and switch the othe wire between to the two other connecters.
hello how to connect if im using input12v and output 12v? possible for this or not?
Hi, it seems you did not understand what I said. We have power for this module to work. Done that is it . it is 12V. to turn OFF or ON relay you can use 1V or 300V it is up to you.
@@robojax ok good cause im planning to drive a 12v fuel pump.
I have connected mine with a push button as you describe but the push button operation does not work. Please help! Griff
It must work if you do it properly.
Hi thanks for this tutorial... Can the 240 volt a/c trigger a device and the 12 volt dc trigger a different device(s) simultaneously?
Hi, sorry I did. It understand. This is van control ONE device. Module is powered up using and triggered by DC. The load does not matter to be ax or dc. If you want o add push button see this video th-cam.com/video/LDLPUpU64J4/w-d-xo.html
is it possible to set the timer for more than 10 second? like around 2-3 minutes
not possible. of course if you remove the potentiometer and pout extra resistor in series, yes it would change. but you have to look at 555 timer schematic and modify it.
When the module turn on, the blue light always on and never off, also the delay off can't be happen. What happen to my module?
good night robojax
with a 5v USB reley I can use it to open an electric lock from my pc
yes you can if electric lock just have ON or OFF switch. You can connect the switch wires to this relay and you should be able to do it.
hey friend
i asked you again where can i find (timer off delay 12v), its very important form me ... please help me ..
this is explaining :
I want the counter start to count when I relase my finger or cut the power?
I mean i want it delay off..
when i press power the light turn on and it countinus lighting until I cut power off then the light turn off after 5second
I replied to your other comment
Where can I buy 3-5 seconds timer switch? Thanks.
see this module th-cam.com/video/s4oNCpH_I0E/w-d-xo.html or this th-cam.com/video/ZRAaTRKRmh0/w-d-xo.html and I have more videos.
You can increase the time by changing the Capacitor to more farads. Delay time formula: T = 1.1RC. For example: Capacitor 22uf resistance 1M T = 1.1 * 0.000010 * 1000000 = 10 seconds.
You may have the exact answer I came looking for. I want to change Seconds to Minutes. So the modules default 60 second max, will change to 60 MINUTES. I'm going to attempt to sort out your formula. Thank you.
@@Lapeerphoto did you conclude if this worked or not, and if so to what degree? I was wondering if I could go to the extreme and make it to +/- 24 hours.
I have make new video with hack showing how to increase the time and add reset switch th-cam.com/video/LDLPUpU64J4/w-d-xo.html
So the adjuster is for the time before it triggers,now what about how long it will stay?
Please watch to get the answer. It seems you have not even watched the first 10 second of the video which I just did. I answer any related question if not answered in the video.
How can I use it as timer circuit,
I need relay to work for preset value,other wise close
isn't this a timer? check 2nd video link in the description to add reset button and increase time.
Actually iam using in making spot welding machine,
So which is best?
this module can handle 10A.
thank you sir
You are welcome.
Sir,
This module works 5v input side?
No. The title clearly say 12V and I have shown it works with 12V . Please watch and I tested it.
Can i use this in reverse mode i e., if i give the power supply the light must ON and after relay turn on (approx after 5 secs) the light must turn OFF , can i achieve this
yes you can. The relay has 3 terminals. NC (Normally Closed), COM (common) and NO (normally open). connect your load to COM and NO and it should word. Watch this video to learn about relay terminals th-cam.com/video/58XWVDnB7Ss/w-d-xo.html
@@robojax
Thank you very much...☺️
you are welcome.
Thanks for the video! There is an option with turning off with a gradual fade instead of simply cutting off the light?
no not possible. this is relay. Relay is a switch with only ON or OFF. you can use dimmer. for that. I have video on dimmer. Here is how to find Specific TH-cam Video in a channel bit.ly/findTH-camVideo
can this work in reverse I need to turn a item on and it turns off after a pre determined amount of seconds. If not can you recomend a module that will do so please? any help appreciated
Yes it can. I believe I mentioned it. the relay has three pins. keep the middle wire of relay unchanged and move the other wire to the other pin. Please subscribe. I appreciate it and helps my channel grow. Thank you
@@robojax Many thanks for your excellent advice Robojax. keep up the good work.
You are welcome. Please subscribe. I appreciate it and helps my channel grow. Thank you
Sir it is possible every one hour for 3 or 4 second please comment
Not possible. 0 to 10 seconds only.
Sir can it be used to close car window for 5 seconds?
it can be used for anything you want as long as the current rating on the relay can tolerate it. so check the relay if it can handle the required current.
Hi, I have a question. With my relay, whenever a power source is applied, the relay switches on immediately, even if i try increasing the time. Any idea why this may be happening?
Hi, may be either the power is weak or it has noise (un clean DC). check if the capacitor pins are not loose.
Can it b set for mili seconds ?...how low can it go ?.. .thank you
this is relay. Relay is a mechanical device NOT electronic switch to be turned ON or OFF quickly. so NO. it can turn on may be twice or trice a second but not more than that. Here I have explained relay and how it is driven th-cam.com/video/N-fFk51Eb8s/w-d-xo.html
The description says 0 to 10 sec so is the proper second or it can b set anywhere between for eg 1.10 or something like that ..and Wat about the other one the display timer relay which has a display and modes can that go to half a second atleast ...and thanks alot good work
this is not exact as there is no actual clock. it is a capacitor where it is discharged via resistor. both capacitor and resistor have tolerance of 5 to 10% so expect 10% error or higer.
Can you give an example of the module turning off
Watch the video fully. I have explained the wiring at 01:30 and explained.
What if power supply is disturbed?
will it act opposite. ?
Or any other idea about . How to give power only for 10seconds.
Regards
So that... I can use this circuit as power saving also
Didn’t I connect it to bulb before connecting power? I should have. It will be off depending on wiring .
I need a circuit.. which can power this relay for like 10-15 second
After that power should off. For the purpose of battery saving.
I'm talking about input power.
Not about output of relay.
Is there any way?
Could you show how to connect this NE555 timer switch for 5 seconds and IR proximity sensor and power source
Hi, that is interesting project but it is very custom and not so many people will use it. I try to make vide3o so many people benefit from it.

Hi, why didn't you search and waited this long? I already have it here th-cam.com/video/LDLPUpU64J4/w-d-xo.html with push button. the push button is the output rom your sensor. watch the video and you can do it.
@@robojax Can i use the similar way to trigger NE555 module of 5v relay ??(could you reply please)

will it work at regular intervals?
no. see other timers th-cam.com/users/RobojaxTVsearch?query=timer
Great video. I want to use this switch to car parking sensors. Reason is because parking sensor disconnects as soon as the gear is put to forward but I want my parking sensor to stay alive for at least 10 sec.
please can you guide for wiring the device? (The output end)
I would really appreciate that.
Many thank
The gear will be needed to be connected to the trigger pin. The relay must be connected to the parking sensor. You will need to select the components such that time is equal to 10sec using the formula T=1.1RC
Hi, were you able to connect the timer relay to the parking sensors? I am looking to connect a reverse camera of my VW using this timer.
Sir i need it for 220V AC.... What would be the circuit diagram
This needs 12V to operate. So connect an AC adapter that gets 220V AC and output it to 12V DC. Then it is a switch to turn your AC bulb ON or OFF and you can connect your 220V bulb as load directly.
Sir from where I can buy it
Check the description. I have provided the link snag.gy/EG4O2l.jpg
Your website doesn't work. I need a triggered relay that will come on for an adjustable time then go off. But cannot be re triggered for a set amount of time. I need it to operate a horn in a Haunted house. Where someone can't just keep triggering the horn constantly. So basically once triggered it will be on for 1/2 second then off for 30 seconds before it can be triggered again. Do you have a relay like this or will I have to buy an Arduino to run a simple relay?
HI, I checked the website and it is working. But you can't purchase. This relay doesn't have both features of ON and OFF. You will need this item th-cam.com/video/dtc4UL2bEs4/w-d-xo.html
3:50 the relay might support 1.8KW but nothing connected to it on that circuit board looks like it could.
Yes. I did the calculation so you know the rating.
how would i connect it so that it only runs for a few seconds and then stays off?
just change the load wires. keep the middle wire and move the other wire to the other connector.
@@robojax I think he means turns something on only for a set period. Power on, device stays on for a few seconds then goes off. Blinking in effect.
Personally, I watched this video because I want to make a 'Steampunk' digital clock controlled by relays that light segments of a hand made digital display lit by old school halogen bulbs. What I mean is, a 1 would be lit by two bulbs on at the left of a figure 8.
How can I increase off time (instead of 10 Seconds)?

the timer circuit works ok with 12v dc motor unloaded but when water is put in the bottle the timer circuit doesnt work
bottle?
@@robojax motor is in the bottle filled with water,a trial for dispensing sanitizer for 2 seconds
its arse about face, really needs the relay to turn on straight away and delay the off time, instead of keeping the relay on to turn everything off then it could be useful to control lights that you only need on for a few seconds or an alarm
In order to do so all you need to do is change the connections of the load and relay.
how can we increase the time delay to 5 minutes.?
Whatever the potentiometer allows to set to maximum that is the limit. If you want longer, you could remove the potentiometer and change it to something different which gill give you longer time. you have to try and find out as we don't have schematic of this device.
Change the capacitor size
It's 7 components on a easily seen PCB you don't need a schematic
Woow
Thanks.

(0:25) - You say that the relay there can be used for an AC or DC load.
No. You are wrong.
Although DC can be used to energize the switching solenoid inside the relay, the actual load ratings for the various voltages that can be switched, (and which is printed on the side of the relay itself), are: 10A @ 250VAC or 15A @ 125VAC .
Nowhere is DC as a load even mentioned.
>
The bulb I am controlling is AC. So yes it can control AC load meaning turning it ON or OFF. Thanks.
@@robojax My point was that the relay showed no DC rating.
My guess is 30v @ 10A DC
OK?
