Thank you, this is great. Amazing how knowledge like this is free on the internet. The modules are dirt cheap as well.
Yes, cheap, fun little click-y things that can do cool things in an electronic project. Thanks for watching the video.
Check my comment 😉
Excellent video ! Thank you.
Hey, I'm glad if it could help!
Thanks for the vid! I'm in the process of researching an install for my car. This is my first time messing with electronics, and I wanted to expand my understanding of what would be happening when I make the install. I discovered via forum that I can use a time delay relay in order to run my fuel pump for longer than the car's computer will allow. This is to accommodate for fuel drained from the lines as a result of a leaky check valve, an expensive and invasive repair.
Ahh, that's interesting. I think these things are probably good for lots of stuff we don't normally think of using them for. If it's not too much trouble, would you mind pasting a link to this comment chain of that forum thread so anyone interested could read up on it? I'm interested in learning more about what you're planning to use it for. Sounds creative and an easy(ier) fix all in one. Thanks for the comment too.
greatly explained sir. thank you.
Thank you for watching
For me it's a multi-amp stereo in my van. If the amps turn on at the same time as the radio, there's always a loud pop. Thanks for the great video!!!!
Thanks for that lesson, you helped me a lot.
Glad you liked it. Thanks for watching!
Great video! It gives me some ideas for sure.
Lots of fun with these even just messing around with them. Thanks for watching!
Very well made video and easy to understand.. much appreciated. I thank you sir. :)
You're welcome. I'm glad you got something out of it. Thanks for subscribing and for the comment!
Chears for the great video. I'm building my own Battery Boxes. To power fridges, lights, etc when camping. I rekkon all the comercial ones are crap. Not fused, no battery protection, poorly ventalated and very expensive. Anyways they all are charged by a DC to DC charger. Problem I hit was I didn't want the DC to DC to start stealing power when I trying to start my Troopie. Found these timer boards on EBay. But like most geeky stuff on EBay there is little to no instruction. So thankyou for taking the time to present this video. I can now finish off my projects. Cheers. :)
Wow thank you so much for sharing this video
You explain so well and put effort in preparing
I don't know much of this but going to use it n my vapour blasting box those is exactly what i need thanls
Thanks a lot for the comment and encouragement. I do appreciate it. These are pretty cool little doo-dads for sure. Thanks for watching.
***** Thank you! I plan to use this to control a timed seat belt reminder light.
"afraid it might be confusing"
this is the first thing that finally made it make sense to me. I didn't know that you could supply voltage on the COM NO NC side all by itself as its own circuit, separate from the whole board being powered by switch on the other side. (the fact that only that side is switched wasn't apparent til you said so, is my only negative).
So to be clear, I can keep something on by supplying voltage via a positive into the COM and out thru the NC to the load to the negative... and then if I send a separate momentary voltage to the input side then I can get that thing to turn off for a moment?
Thanks...from Indonesia 👍
Thanks for the video. I'm thinking of using a couplle of these to control a couple of contactors I'm using for an electric motorcycle build. One contactor is used in a pre-charge circuit, while the second is used for the main power circuit. Both are in parallel between the battery and motor controller.
Sounds fun. I was just playing with one of these myself today getting ready for another radio build. As long as your voltage and more importantly, amperage needs are under the max on the timer relay, it should work well. Feel free to follow up here if you want on how it went once you get it functioning. Thanks for the comment!
thank you well explained I can use it in the car I have a small amp for the bass speaker and it makes a horrid noise when I crank the car over.
Great video 👍
Thanks!
Congratulations on your great project, what kind of resistance Ohm did you use?
I need to set up a time delay relay with a reset? I want to make low voltage led light flash. Any ideas? Thanks for the video!
Great video. I’m using one of these to power up an inverter. When it’s turned on the n/c terminal connects through a resistor to precharge it and then after 4 seconds a continuous duty solenoid is activated by the timer through the n/o terminal to connect full voltage.
Nice. That's a clever use for one of these. Thanks for describing your use of this cool little device. These things are handy little buggers. I plan on using one for the radio I'm in the process of building. I may use it to delay the amp power-on, or I may connect to the common (-) terminal of the amp output and just let the amp turn on right away and delay the speaker connection. I have to see if that will work though first.
Thanks for the comment Adam, and thanks for watching my video.
thank you sir!
Very informative helpful video! Being very green to electronics I purchased this item without knowing it's not the greatest for my application. What sort of device would I be looking for to turn on a 12-volt beacon approximately 10 seconds then shut off? Using a Banner photoelectric sensor to trigger when an overheight semi hauling heavy equipment passes through it. TIA
That sounds like a fun project... I don't know exactly what device would do that, but I bet a search on Ali or Amazon would yield a solution. There are delay turn off devices as well, maybe it could be that simple. Good luck!
Hello sir, i do not able for work this delay, i try again, again. After looking your video it work good, wow. Thank you for your demo, it easy to understand how it work. Now work good, youpi, i put on my target, when i shoot whit the rifle 22lr. View from Quebec, excuse my for my english. Appreciated your time for this video, good job my friend!.
Hey Gaetan, I'm really glad that it helped you understand how it worked. Sometimes I have to see things in a specific way to understand it, and that's why I made this video. I have a video coming up where I will use this relay, so stay tuned! Thanks again for the comment!
Hi,
I'm looking for a timer module similar to this one, but I need the opposite of what this does. I need a module that switches on the relay immediately when power comes into the module and keeps the relay on for a couple of seconds after power is removed from the module. I'm able to supply an additional continuous 12v power line to keep the relay on.
I've thought about this for awhile, but I can't seem to figure out how to do this with anything I could find. You might be able to do it with an Arduino board, but that's beyond me, and probably more complex than you want.
Not sure if this would work, but maybe check this thing out... www.amazon.com/DROK-Controller-Delay-off-0-01s-9999mins-Adjustable/dp/B07RGT5G1X/ref=sr_1_14_sspa?keywords=time%2Bdelay%2Bswitch&qid=1692563971&sr=8-14-spons&sp_csd=d2lkZ2V0TmFtZT1zcF9tdGY&th=1
Congrats for this fantastic explanation!! I would like to ask whether this relay can get activated with 6-9 dc Voltage in it's input, rather than only a fixed 12 dc Volt. I want to activate it with a rechargeable 9volt battery for my project. Would it work? Thank you!
Check Ali or Amazon for different voltages in this item. They have 5 volt versions as well.
Hi, iv just purchased 2 of these, but mine have zero voltage out once the relay energised and the second light comes on, but the 2 inner legs of the relay energise after the set time, do they do 2 versions of this that look identical, , so mine have zero output once the 2nd light comes on, and both work the same. thank you.
I've purchased so many things from Ali that looked/worked one way, then purchased another from the same seller even, only to find that there are differences one from another. It wouldn't surprise me one particle if you got one that worked differently than the one I demo'd. As long as you can figure out how it DOES work, you should be good. Thanks for watching and commenting!
thomas can you draw up a diagram for a door security alarm using 12volts and a on/off switch with this type of relay so that when the door is open the bell will still sound until i switch it of myself, i am not good with this type of stuff
I think you just need a 'normally open' security door switch which does not complete the circuit until the door is opened. Search for "N.O. security door switch" on Amazon for some ideas. You can use that switch to supply 12 volts to the 'power in' side of the relay board. Wire it so that the relay will see voltage when the door is opened. Black ground wire from the 12 V power source goes right to the input side of the relay board, and the positive 12 V from the power source goes to one side of the "N.O. switch" and then the other side of that switch goes to the (+) side of the relay voltage input.
...so... when the relay board sees 12 volts from your door switch, it will time out depending where you have it adjusted, and then connect the 'common' and top 'on' taps on the left side of the relay board. You wire your buzzer 12 volt negative from the power source right to the buzzer, and then the 12 volt (+) will go through the 'common' and top 'on' terminals on the relay board. That 'should' get you there. You can add a switch to interrupt either the 'Power In' the relay board, or the 'power out' to the buzzer, whichever works easier for your needs. Sorry, I can't post a diagram or picture here. Hope this helps!
I want to delay the amp off on my car amplifier using the radio. Remote on. I want the amp to turn off 10 sec after the radio powers down. Does the relay get constant power? And what pins would I hook up for this to work, thanks.
I don't think this would work for what you need. Once power is cut to this relay board, the power is cut to the switched device instantly. This only delay's the "ON" procedure.
I plan to put one on an audio control dm-608 dsp before it turns on my car amp to prevent the start up pop I sometimes get
I'm trying to setup a time delay on a toilet flusher with 24 volt power. Basically I'm hoping to press a button and have it flush for 5 seconds (engage the solenoid)
Any recommendations? The board I got didn't work out for me
Hey Marc, Check this item out: www.aliexpress.us/item/3256802427017605.html?spm=a2g0o.productlist.main.55.818e2d109ZRzKL&algo_pvid=24af2e47-9763-4618-9680-6e4c945748bc&algo_exp_id=24af2e47-9763-4618-9680-6e4c945748bc-27&pdp_npi=4%40dis%21USD%214.92%213.49%21%21%214.92%21%21%402101d4a716979757808453712e1d6f%2112000021396436345%21sea%21US%211618196486%21&curPageLogUid=hN66kIawbziv#nav-specification
I'm not sure if this is what you need, I can't really tell from the description. But if you look for similar items on Ali you will probably find what you need.
Thanks for watching and commenting!
hello bro, can this be used to contact motorcycles that use the solenoid system?
thank you in advance, my warmest regards from Indonesia ️
Is there a board like this with 4 terminals? I want to use something like this to control my model railroad 3 aspect signal, green, yellow, red through this timer relay.
Not that I'm aware of, but I suspect you could use two or three of these set at different time intervals to do the same thing? The relay connects the middle and bottom terminals when off, and disconnects when turned on, so could you use that to your advantage?
@@zarboaudioprojects1430 yes that is a thought thanks
Which time delay board should I use in my car audio set up, the 5 volt or 12 volt?
I'm not sure what you're planning to do with it, but for a car, I'd say go with the 12 volt unit since that's what your car is wired for. Just make sure whatever you're trying to switch doesn't exceed the current/voltage capabilities of the relay mounted on the board... it should say right on the relay itself what it's limits are.
so do you increase the capacitor to get mor time or decrease it i want about 5 min timer
Sorry for the delay, you will need to check with the seller... some of these work differently and they change how they are made without warning, so best bet, ask the seller. Thanks for watching!
You should've shown the schematic diagram for this module .... they are very useful and have many uses ... I have one I designed myself and it's used as an inrush current limiter, shunting a group of power resistors in a 1Kw audio amp I built.
Thanks for the comment and for watching!
hey janina can u send me the diagram pls.I need it for my project
I had to watch a few times and really pay attention before it sank in. I'm not an "electrical" guy. Is this same as a "soft on" or "soft power up"? Would you recommend using one in the 2.1 build you just did? My parts just came in and I'm starting to get that itch.
It could be used as a soft start option for an amp. Or, I suppose you could use this to switch on the ground line of a L(eft) R(ight) G(round) input to an amplifier so that the amp would still turn on right away, but the signal wouldn't get to it until the delay time was over. It depends on what 'thumps' or other noises your intended equipment makes and when.
I'd like to make a delayed start signal for a project but I can't wrap my brain around these timers offered on Amazon.
I have an inverter (Schneider Electric XW+) that will use a battery bank to power my critical loads. It can also get power from a generator that it will start when told to do so.
I want to connect a 12vDC relay to a power adapter connected to a grid outlet, that is, not a critical load outlet. When the power goes out the relay will switch and the normally open connection will close. That's the trigger that the grid power is out.
That trigger needs to delay start the generator after grid is down for 15 minutes by momentarily closing a connection on the inverter. However if the grid comes back up before the 15 minutes then everything is canceled, that is, I don't want to signal the inverter to start the generator.
Another delayed timer relay is to stop the generator after the grid is up for 15 minutes. If it comes up and then down again before the 15 minutes, then nothing happens. But if the grid stays up for 15 minutes, (12vDC relay connected to grid power adapter is on), then a different connection on the inverter is momentarily made signaling it to stop the generator and return to using grid power for the critical loads.
Your application for a time-delay amp turn for the radio was well explained. I enjoyed it.
Any thoughts, comments, ideas, etc. will be appreciated!
Thank you
I bought some strobing red LEDs that I was going ro wire in to the brake light on my scooter but the regulations for flashing brake lights require that they only come in when emergency braking. I found this video looking for ideas and now I think I have a plan! If I run this circuit off my standard brake light feed with a delay of 2 seconds then have it switch the strobing lights on I think I can have F1 style brake lights that might just be almost UK legal!
Sounds like it would work as long as the strobing lights are different than your main brake lights. Good idea!
Well mine finally arrived from China. My plan is to tap the live feed to my rear running light as that's always live whenever the ignition is on and use that to power my strobe light wiring the tap thru the output on this board and up to the strobe then tap the power line from the rear brake light and run that to the input on the board. I hope that makes sense! That potentiometer takes some bloody turns to take notice!@@zarboaudioprojects1430
I have an older 1970's pickup truck, what I'd like to do is have the dome light stay on a few seconds after the door is shut. Like in a newer vehicle. Would this work for me.
I don't think this would do what you want it to. Once the power is cut, the light would go out.
Am having big issues with mosfet getting so hot and i when to use relays for my hho generator cause relay down get overheat fast as mosfet so I like this system
Sir, is it possible to Adjust the time to 1 minute up ??
Sorry I didn't see this comment sooner. Check this video out, it may help: th-cam.com/video/LDLPUpU64J4/w-d-xo.html
I got one of these but no matter how many turns I adjust the screw, I’m unable to change the delay time
You might have a bad one. But just for fun, try screwing it all the way out, or anti-clockwise, then going clockwise again, I had one on which that worked when it wasn't adjusting the first time. At least they're cheap! Thanks for watching and commenting.
Kindly provide the circuit diagram best regards
Can 12v relay work with 18.5v dc input voltage?
It likely cannot handle that much voltage. Instead, check this product out for a minimal cost increase... www.aliexpress.us/item/3256801531648436.html?spm=a2g0o.productlist.main.25.12b074deVELEXr&algo_pvid=885889ed-6f5e-4171-8e5a-0beab02fdfa4&aem_p4p_detail=202308250644598694424702336800004255246&algo_exp_id=885889ed-6f5e-4171-8e5a-0beab02fdfa4-12&pdp_npi=4%40dis%21USD%215.40%211.3%21%21%215.40%21%21%402101f49416929710997604513efba0%2112000017311197157%21sea%21US%211618196486%21&curPageLogUid=Dg5Z4bzZvWJK&search_p4p_id=202308250644598694424702336800004255246_13 Thanks for watching!
Just use dc-dc converter module step-down output
Input- 18.5V output 12V
hi! want to know the different between this and mos ?
Sorry, I'm not versed in metal oxide semiconductors.
tnx
Can this device be used as Horn Interrupter?
As in a car horn? I'm looking at the 12 volt time delay relay board right now and it the relay on the board shows the ability to switch up to 10 amps at 30 volts. So it does sound like it might be feasible as long as the horn doesn't draw more than that amount of current.
@@zarboaudioprojects1430 For Motorcycle.
Yesterday I bought the item online, but when I tried the blue led light and the relay didn't respond, I wanted to return the item, but the seller refused on the grounds that the item was new and still sealed.
Well explained. I have an EV car that has an annoying back-up warning. I want to be able to press a button to temporarily disable the back-up alarm when I back up out of my driveway at 4am so as not to wake my neighbors, but I want the back-up capability to return back to normal on its own. That way, instead of using a simple on/off I would never forget to return the back-up alarm to its normally on state. There are situations where I want the back up alarm on (backing out at a busy parking lot) so I never want to forget to turn the back-up alarm on.
How can I increase it's OFF TIME from 10 second to 5 minute?
check out this video, it may help with that: th-cam.com/video/LDLPUpU64J4/w-d-xo.html
