NE555 Adjustable Delay Timer Switch Module 0-10 Second 12V

Description: NE555 Timer Switch Adjustable Module Time Delay Relay Module DC 12V Delay Relay Shield 0~10S NE555 Time DC Specification: Size: 6.8CM *2.1CM Main Chip: NE555 Working Voltage: 12V Features: 1. Power relay delay pull. Specifically:12v power supply to the relay, the relay will not immediately sucked and status relay outputs are normally open disconnected public,normally closed and public conduction,wait until the delay 1-10s (adjustable),the relay suction and, this time, the relay output status is: normally open and public conduction,normally closed and public disconnected; as long as uninterruptible power module, this state will remain. 2.Delay time is adjustable(0 to 10 seconds) 3.Increasing the potential can increase the delay time 4.Increasing the capacitor C1 can increase the delay time 5.With input power indicator 6.With relay indicator 7.Can control AC 220V / 10A about equipment. (Maximum control equipment 2000W) 8.With freewheeling protection relay. 9.Delay time formula: T = 1.1RC. For example: a resistor capacitor 100uf 100K What you will receive: 1 x NE555 Timer Switch Adjustable Module
