Your cart is empty. Protect your equipments with this tiny 12V time delay relay circuit. The SMPS based power supply of these modern electronic devices is vulnerable to spikes in the mains line so it gives a time delay of one minute before applying power to the device. This prevents deleterious effects due to inrush current and spurious spikes at power on.
Technical Specifications:
Operating voltage:12V
Trigger: When the trigger end of the module senses that there is a switch closing trigger, the module starts the delay function, and the relay draws in. At the end of the delay, the relay is disconnected
Output capacity:can control the DC 30v/10A or AC 250v/10A equipment
Quiescent current:20mA
Service life:more than 100,000 times
Operating temperature:-40-85 ℃
Delay Time Range: switch S1, S2, S4 to different positions, potentiometer can adjust different time range. The specific adjustment method is shown in the picture.
Module size: 56.5mm X29.5mm X 18.5mm / 2.22×1.16×0.73 inch(L * W * H)
Operating Method:
1. Put S1, S2, S4 in the proper position, adjust the potentiometer to adjust to the time you need.
2. When the trigger end of the module senses that there is a momentary closing of the switch, the module starts the delay function, and at the same time the relay pulls in and the delay ends and the relay recovers.
3. When the module is triggered for delay, if a trigger signal is received again, the module will re-time until the delay ends.
Package Includes:
2 X DC 12v Delay Relay Switch

to a little extended-timing function I was looking for as part of a proof-of-concept modification to a car climate-control package. Works exactly as described, with easy configuration via jumpers and a small potentiometer.Need a longer delay duration than a 555 or series 556 timer will reliably deliver? This is an easy option.

As is usual with electronic parts from China the documentation is lacking. This one has none at all but if you have any electronics sense it can be figured out and made to work as designed and sort of as sold. I gave it three stars for easy to use because of the "No Instructions". I gave it fours starts because the timer was not as stated in the description, but close enough for my project. And lastly I gave it five stars for value. Over all a good buy.

This product is everything I come to expect from Chinese electronic items sold on Amazon. Neither of the items received worked as described. No timer function what so ever. Relay only functioned as an instant on power switch regardless of jumper placement. Totally useless and a waste of my time, effort, and money.

This Timer Relay is Quite handy. No instructions come with it but the seller provided jumper information in the description, The timer is pretty accurate, and consistent. I just got these today (09-01-2020) and tested them but I can't speak to their longevity or dependability, That being said they seem to be well constructed and they definitely do the job i had for them. I do recommend them. one thing iI found out by trial and error is that you can trigger the relay with one wire from vcc to trigger pin closest to the center of the relay board, (the pin next to the power supply blue block).

Relay pack works great, Heed the reminder to watch you voltage.

Had to return because would not operate how it was needed. Ordered another type.

OK gave this an initial 1 star due to vague description (using 12v dc), but after adding a transistor(2n2222) to the trigger of the relay with a 250k ohm resistor to the base was able to consistently trigger the timer circuit with no issues.

Great timer circuit
