Programmable triggered timing board 35238 MP 

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 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.

Thanks, bought a couple of these from amazon and of course, not one letter of instructions. You made it easy!

You are wonderful! I truly appreciate your complete explanation and also showing how you wired the darned thing!!! Thank you 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 helpful video. I will definitely be buying some of these from MPJA.

Thanks for the video, best explaining video of this module I've seen so far

Thank you for making this tutorial so simple and understandable.

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.

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. 👍

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.

Excellent tutorial. THANK YOU!

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!

i want to like this upload twice.... just perfect thankyou

Finally, somebody explained nicely thank you 🙏

Great tutorial. Thanks! The instructions in the chinese pages for this device are all but unintelligible and were driving me crazy.

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.

My unit only counts up -not down-is there an undocumented setting? I have looked all over!

the mosfet on that module is really hot. really need to put a heatsink to dissipate heat

Sir you had not shown us how you connected Dc power cable to the circuit clearly. How trigger is connected to which terminals.please do so.

How do I stop the program name from showing up every time I press the trigger?

can this be hooked up with a motion sensor and a nine volt battery supply?

A list of what each function did would be nice

I have the top two terminals on the left connected to a 9v battery but nothing lights up (no power). I can get it to light up via the micro USB power input. Am I doing something wrong or do I have a faulty board?

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,?

How fast can this timer cycle? I have a hopper feeder im working on. I want to hit the button and have it send 3 rapid fire pulses and then stop. I would also like it to continuously send pulses if the button is held down. Is this possible?

Hello, is it possible that a certain program runs "at boot" time. I want to basically use this as a trigger for my start/stop disable button in my car. So after 10 seconds of car start to auto press the button. Would that be possible?

So where do you connect your load? Is it in those NC COM or NO COM?

can we use it for switching on a device continuously with a delay . say 1-2 sec delay

i have a question, sorry about my english. i have a problem with that timer, i have conected all properly, the timer goes on, all good, i have already programated 10 secs, i push the trigger and the time go faster than 1 sec. like 0,5 sec. the same with minutes. i dont know whats wrong. do you have an idea? i hope u can understand me.

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.

Amazon sells similar boards which also have low voltage trigger and one extra connection point on the left. Does anybody know, is it a different chip, or low voltage trigger achieved differently ?

Hi do you know why it loops 6 times when I set it to 3 times

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

Is the program persistent if the unit loses power?

Mine doesn't seem to work( at any setting relay turns on for like 0.1 second, then shows which program is running. Timer doesn't come up at any setting. Timer seems to work only when you press Stop to turn off the relay.

I know this is an old video but I have a question about p4 because I think that's the one that will be useful for me I'm trying to get my car stereo to not reboot when I start the car does this sound like it would work?

Does this have memory. If you remove power does it remember the settings when reconnecting power?

whats the functions of the usb port can we get some pc controlled project fun happening

the mpja link above does not work :(

Can this timer be used for a freezer door left open for say 5 minutes then ring the alarm. And if door is closed within set time and door is then closed timer resets. No Pizzo buzzer noise. Trying to make safety for the freezer door. an open door led light comes on. What I want is if the door is not closed in a set amount of time the timer then would go off and send power to the Pizzo buzzer.

Great tutorial! I do not see the functionality I'm looking for. Is there a way to set the following behavior? ON with trigger (in my case a short .5 second burst) then ignore any other triggers for a set period of time?

Can you add a delay on then constant on

Dear my friend, when you trigger the delay circuit the countdown is running if you give it a 2nd trigger it stops. Any idea not to stop the countdown. Regards

How is this wired to the device? I cannot get the motor to turn on. I am wanting to use a smaller RC car motor set up.

Is it possible to use it in opposite way. First should be closed time and than open time.

so you can hook this up to a sensor via the trigger pin to turn on the relay? Basically I want the RCWL- 0516 sensor to turn on the relay (no delay) and run for 6 seconds so it powers on a musical box movement and turns off after 6 seconds

Please anyone answer my question 🙏 Which points are shorted by the black wire?

Hi, can i use this with a nodemcu 8266, i need to control a water pump that will turn on when the humidity reach a certain point. But i only need the relay to turn on for a few second, to avoid an overflow.

Hello sir, I'm just trying to use this delay module, but when I do the steps as you explained, my counter is increasing instead of decreasing, can you please help me out Thank you so much

What is the actual board number on the back? This is practically identical to the JZ-801 board, except the JZ-801 has programs 1.4 (triggered single cycle, no retrigger) and 2.1 (delay w/ retrigger).

Is there anyway to test without hooking it up to anything else except the switch?

Why two grounds?

Which one program is pause and resume?

Handy video. Thanks.

Can I set this to run for 10 seconds at the same day everyday?

I hoped this item would work for me, but my trigger signal is inverted. I need the function of P4, but my trigger signal is always on, and the trigger would be a short off pulse. I think it would work if there is a P4(.1) with instead of OP, a CL variant. Otherwise I would need to use a second relay to invert the signal. Any suggestion for similar products, or modifications?

Good info.

I’m operating on p3.2 to power a 6v motor, why do I not have voltage??? I’m wired just like the video with 6v power and the program is correct and running. Where do I wire the motor in? Do you have a diagram?

I have been using this device in Program option P3.2 successfully for almost 2 weeks. However, tiday it has developed a problem. My PL time was 15 minutes and CL was 90 minutes. I had set Loop 120. Today the PL count down starts and then it trips and starts all over again from 15. It is not going to CL mode. BUT when I tried testing it in seconds instead of minutes it works fine. Also while testing I noticed that when the loops finished the switch stays in PL mode. Any advice anyone? Thank you

I've used a handful of similar timer modules but I just bought some of these and I'm very confused because I don't see any logic chip to handle the programming and display! What part of the board is controlling that? I don't believe anything is hidden out of sight Edit: Nvm the chip is hidden beneath the display! That was driving me crazy

Hi do you ahip to Barbados?

Is it possible to combine time ranges? Say you use P3.1 and want a on time of 0-999 seconds, but an off time of 0-999 minutes?

Very useful, thank You!:-)

Como programar led da XY-J02 para ficar aceso direto?

Thanks a lot. This was very helpfull for me. :)

How to increase display time in settings

Can you mix time modes for ON and OFF? I can't see that you covered that. For example, can you set the ON time in 0-99.9seconds and the OFF time in 0-999minutes? If one can, you may wish to point out on your website feature list that these are independently assignable. You do KIND OF suggest this in your datasheet/UserManual (and THANK YOU VERY MUCH for providing it on your website) but it's not obvious. You merely state, _"It is configured in exactly the same way as the OP function."_ (and I'm assuming one can still enter infinite loop mode...and I'm just stating this because sometimes when users do "unexpected" things like this it breaks program subroutines) For example, I want to run a pump for 30 seconds TWICE per day, everyday. So I set *ON=30 seconds, and OFF=719 minutes, infinite loop* (note, I realize these actually add up to 1439 minutes (2x30sec + 2x719mins) instead of a day's exact 1440 minutes, but it demonstrates what I mean. With these settings, the ON times when observed relative to a realtime analog clock would be slowly moving around the clock...in other words, "ON" wouldn't happen at exactly the same 2 times every day.)

Thanks a lot man, helped a lot

Hi there, fantastic video - very helpful - thank you. Is it possible to get different versions of these with alternative preset options? Can you get one that loops P2 for example - this is what I need?

how to reset a programmed function?{defalt]

Kaha milega ?

Perfect 👍🏻 I have

thanks Man

God bless

Great

very well explained, it has been very useful, thanks

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!

I was just thinking to smash this item till ifound you!!!😂😂❤❤

thank you sir, it really helps me to understand the function of this.

How many amps can pass through it?

LIFESAVER --- Thanks for posting this...

This is perfect , 3.2 is the program I was looking for 👍😁

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.

Great video! Very well done. Easy to understand. Saved me loads of time. Thanks!

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

Excellent. These module type instructions are sometimes hard to follow. Thanks for working through the different programs.

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.

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 =/

This explanation was easy to understand. Thank you very much.

I gotta say, your a life saver😎😎 I have one of these and boy lemme tell you its confusing; however you make it simple and relatable!

Finally someone explain it probably. Thank you for that educative lesson. How do you rest the whole thing ?

Thanks dude, that's really helping me

Some day in the far future they might start issuing directions with these type of devices.

Sir, can this device be used to make an led flash, say for 3 seconds, and then countdown from an adjustable amount, in a continuous cycle without pressing a button? Ideally I'd like to be able to control both the interval, and the duration, can it do that? Regards Mark.

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.

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!

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

Hey I know this is an old video but I'm hoping you can answer a question about this device... Does it remember the mode and time settings if all power is removed from the device? I.e. when it's hooked up to power next time, is it still in the previously used mode and time delay?

Could not have done i without your video! Thank you.
