5V NE555 Time Relay Shield Timing Relay Timer Control Switch Car Relays

Product Description

1. Size: 6.8CM x 2.1CM 2. Main chip: NE555 3. Working voltage: DC 12V/5V Features: 1. The relay time delay and power supply is connected.Specific as follows: for 12V/5V power supply to the relay, relay not immediately and absorption, relay the output status to: normally open and public disconnect, normally closed and public conduction;Wait for delay 1-10 s (adjustable), relay and absorption, at this point, the relay outputs status to: normally open and public conduction, normally closed and public disconnected;As long as the module power continuously, this state will remain. 2. The delay time is adjustable, (0-10 seconds) 4. Increase the potentiometer to increase the delay time 5. Increasing the capacitor C1 can increase the delay time 6. With input power indicator light 7. With relay pull-in indicator light 8. It can control AC 220V/10A equipment. (Large control equipment 2000W) 9. With relay freewheeling protection. 10. Delay time formula: T=1.1RC. For example: capacitor 100uf resistor 100K T=1.1 x 100000 x 0.0001=11 seconds Applications 1. The on-board equipment on the time delay, prevent excessive current when the car lighter burned on-board equipment. 2. Need to have order to start the occasion, to prevent multiple devices at the same time starting current is too large burning appliances.
