Your cart is empty. Specification:
Size: 6.8CM * 2.1CM
Main chip: NE555
Working voltage: 12 volts DC
Characteristics: 1. Connected to the power relay to 1-10s fixed cycle pull and disconnect. Specifically: to the relay for 12v power supply, the relay will immediately suck and relay output status: normally open and common conduction, normally closed and disconnected; until the delay 1-10s (can be adjusted), the release of the relay , At this moment, the state of the relay output is: Normally open and common open, normally closed and common conduct; As long as the module is not powered off, this state will keep and release with fixed cycle of 1-10s.
2. Adjustable delay time (0 ~ 10 seconds).
3. Increase the potentiometer can increase the delay time.
4. Increase the capacitor C1 can increase the delay time.
5. With input power indicator.
6. With relay pull indicator.
7. Can control the exchange 220V / 10A about equipment. (Maximum control equipment 2000W).
8. With 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:
1*NE555 DC 12V Delay Timer Switch Adjustable Module

Does as described and delays powering on the relay by adjusting the multiturn potentiometer.

Applied 12V to the first one and it stayed on the whole time. I adjusted the voltage and found that it would only switch around 9v no matter how much I adjusted the potentiometer. If I turned the voltage up it would click on and off while the voltage was changing but then just lock in the ON position.Device two - applied 12V and it click on a delay. I increased the delay time and it clicked again when I reapplied power. I turn the potentiometer one more time and it stayed on. I turned it back and it was instant on again. completely unreliable!

These are TRASH! Went through 3 of these. This is like the toys you buy your kids at the State Fair... last abt 10 seconds. They test fine with no load, but as soon as you connect something, in my case a low watt bulb, the delay timer stops working and it starts tripping immediately. It's probably the microprocessor, but it doesn't matter. Trash!

I wanted a timer to engage power after a period of time and this worked fine. I had to power a computer in a car but wanted the power to come on after the car started to avoid voltage irregularities. This device allowed the car to start and regulate before power came on.

The ad is misleading. It says 800 items, but there is only 1!

Well made. Convenient screw terminals for quick and secure wiring. LED lights indicate power on and relay engaged. Came wrapped in anti-static bag for protection. Works perfectly.
