DC 12V Delay Relay Shield NE555 Timer Switch Adjustable Module 0~10S for Arduino etc. ***LOCAL STOCK

DC 12V Delay Relay Shield NE555 Timer Switch Adjustable Module 0~10S for Arduino, Raspberry Pi DIY

Size: 6.8cm * 2.1cm
Main chip : NE555
Working voltage : DC 12V

1, Power relay delay pull. Normally: 12V power supply to the relay, the relay will not immediately start and status relay outputs are: normally open and normally closed.
2, The delay time is adjustable, (0 to 10 seconds)
4, Increasing the potential can increase the delay time
5, Increasing the capacitor C1 can increase the delay time
6, With input power indicator
7, With relay indicator
8, Can control AC 220V / 10A equipment. (Maximum control equipment 2000W)
9, With freewheeling protection relay.
10, The delay time formula: T = 1.1RC. For example: a resistor capacitor 100uf 100K T = 1.1 * 100000 * 0.0001 = 11 seconds
