Your cart is empty. Specification:
Module chip: NE555 chip
Delay modue: delay connect module
Input voltage: DC12V
Control voltage: AC 0~250V / max
10A, DC 0~30V / max
10A the operating voltage: 12 volts DC; (otherwise 5V optional)
Max load: 2200W
Applications:
Vehicle equipment-delay to prevent car ignition, prevention of high sudden current to burn components and devices.
Module performance and features:
1.Turn on the power relay and delay the pull-in. Specifically: after supplying 12v power to the relay, the relay will immediately suck and relay output status: Normally open and public disconnect, normally closed and public conduction;
wait until the delay is 1-10s (can be adjusted), the release of the relay and at this time,
the state of the relay output is:
Normally open and public conduction, normally closed and public disconnect; this state will be maintained as long as the module is continuously powered.
2. The delay time is adjustable, (0 ~ 10 seconds)
3. Increase the potentiometer can increase the delay time
4. Increase the capacitance C1 can increase the delay time
5. Possess of input power indicator
6. Possess of relay pull-in indicator
7. can control the AC 220V/10A equipment. (Maximum control device 2000W) 8. Possess of relay freewheeling protection
9. Delay time formula: T=1.1RC. For example: Capacitance 100uf resistance 100K T = 1.1 * 100000 * 0.0001 = 11 seconds
Package Included:
6 X NE555 DC 12V delay timer module

It is a good thing that you get multiples in the set. I bought the set of 5 5v. 3 of the 5 do not work. the relay does not switch on 2 of them, the other has a bad capacitor. the solder on these is poorly applied. I added the wiring diagram to my review as they do not provide a diagram.

Worked fine for me (worked great for delaying 5V to a peripheral by a few seconds), but I only tested 2 of them out of 6. The relay is activated after the chosen delay following 5V VCC being applied, and it has the usual NO/NC lugs except they're labeled CB/CK. Turn the potentiometer screw clockwise to increase time delay (it takes many complete turns to get from 0 to 10 seconds).

I tested this on my bench power supply. I applied 12 volts, saw the relay kick on after about 7 seconds followed by the led blowing and the relay no longer working. Comparing this to the similar 5v models I have and they appear identical. They were drawing .2 amps at 12v with the led being very bright. Do not buy.

All six ended up being defective. Some didn’t work at all and some worked a couple of times and then just quit. Must be rejects that failed testing.

I usually have to throw away one defect from each batch. Other than that, they work perfectly for my needs. You can change out the capacitor for a longer timer. I need at least 40 seconds and stock never gets me more than about 15 seconds.

Make sure you save the diagram shown in the listing so you know how to wire them up. Hey didn’t I’m with any diagrams but I was able to reference the listing. They work well. My only gripe is the lack of documentation with them.

They function exactly as the listing describes. Easy to wire, easy to use. However, only two out of the six that came in the package actually worked, the other four were complete non-functioning duds. Even still, not a bad price just for the two that worked.
