Size: 6.8cm * 2.1cm
Main chip: NE555
Working voltage: 12v DC
1. Delay time adjustable (0- 10s)
2. You can add the delay time by adding potentiometer;
3. You can increase the delay time by increasing the capacitor C1; 
4. With the input power indicator;
5. With relay actuation indicator;
6. This relay can control device below AC 220V/10A (Max 2000W)
7. With relay freewheeling protection;
8. Delay time formula: T = 1.1RC. For example: Capacitor 100uf resistance 100K T = 10.1 * 100000 * 0.0001 = 11s
9. When the power is on, the relay is time-delay closing:
When you offer 12v to the relay, it will not pull in immediately and the output status >>Normal open is not connected with common, while Normal close connected with Common; after 1-10s(adjustable) delay, Normal open is connected with Common while Normal close disconnect with Common.
1, Apply with mobile unit, delay the connection to prevent excessive current damaging the device;
2, Prevent burning appliances when multiple devices are simultaneously starting and causing overcurrent.
