1 x Delay Module
12V Delay Suction Close Relay Module
1. Size: 6.8 CM * 2.1 CM
2. The main chip: NE555
3. Working voltage: DC 12V
1. Turn on the power relay time delay suction together.
2. Delay time is adjustable, (0 ~ 10S) SECONDS
4. Increase the potentiometer can increase the delay time
5. Increase capacitor C1 can increase delay time
6. with input power light
7. Has the relay suction close lamp
8. Can control ac 220V / 10A the equipment. (Maximum control equipment 2000W)
9. With relay fly-wheel protection.
Delay time formula: T = 1.1 RC. Such as: capacity 100uF resistance 100 k T = 1.1 * 100000 * 0.0001 = 11S
