Description：
Size: 6.8CM * 2.1CM
The main chip: NE555
The working voltage: 12 volts DC
Characteristics:
1. Power relay 1-10s at a fixed period of closing and opening. Specifically: 12v power supply to the relay, the relay will immediately suck and state relay output is: normally open and public conduction, normally closed and public disconnect; until the delay 1-10s (adjustable), the relay releases in this case, the state of the relay output is: normally open disconnect with the public, normally closed and public conduction; Just uninterruptible power module, this state will remain in a fixed period of 1-10s pull and release.
2. The delay time is adjustable (0 to 10 seconds)
3. Increase the potentiometer can increase the delay time
4. Increasing the capacitor C1 can increase the delay time
5. With the input power indicator
6. With the indicator relay
7. Can control AC 220V/10A about equipment. (Maximum Control Equipment 2000W)
8. With a continuous flow protection relays.
9. The delay time formula: T = 1.1RC. For example: Capacitor 100uf resistance 100K T = 10.1 * 100000 * 0.0001 = 11s
