- The timer delay is made of electronic accessories, inner conductor is pure copper. it is long lasting and durable for you to use.
- 12V module, the output can be connected to AC 250V 10A and DC 0-30V/max.10A equipment, and the max control equipment is up to 2200W.
- NE555 delay module, which consist of high-precision potentiometer ( adjust the output frequency.), high frequency filter capacitor and with input power indicator, with the relay is energized light .
- The timer switch relay module can be adjustable timer delay(default setting:0-10s) and counter clockwise adjustment of potentiometer to increase delay time. Useful for applications in equipment-delay to prevent sudden high current which can burn components and devices.
- A wide range of applications: The adjustable timer switch relay module is designed with relay module continuous current flow protection. This module is perfect for SCM learning, electronic competition, product development, graduation design and so on.

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.

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.

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.

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.

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.

good product only problem is there was no wiring diogram
The Engineer Critic –
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 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.
