Relay Module 12V Timer Delay NE555
Relay Module 12V Timer Delay NE555
Adjustable Precision potentiometer to set the time of the relay to switch ON.
Operation: The relay will switch ON when power is applied, and switches OFF after the preset time.
Specifications and Functions:
✅Operating Voltage: 12V
✅Delay time adjustable (0- 10s)
✅You can add the delay time by adding potentiometer;
✅You can increase the delay time by increasing the capacitor C1; With the input power indicator;
✅With relay actuation indicator;
✅This relay can control device below AC 220V/10A (Max 2000W)
✅With relay freewheeling protection;
✅Delay time formula: T = 1.1RC. For example: Capacitor 100uf resistance 100K T = 10.1 * 100000 * 0.0001 = 11s
✅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.
