Your cart is empty. Description:
Size: 66*21*12mm, Weight: 9g
Main Chip: NE555
Operating voltage: 12V DC
Feature:
1. Turn on the power relay and delay the pull-in. Specifically: after supplying 12v power to the relay, the relay will not immediately suck and relay output status: Normally open and public disconnect, normally closed and public conduction.
Wait until the delay is 1-10s (can be adjusted), the relay will immediately suck and at this time, the state of the relay output is: Normally open and public conduction, normally closed and public disconnect. This state will be maintained as long as the module is continuously powered.
2. The delay time is adjustable, (0 ~ 10 seconds)
3. Increase the potentiometer can increase the delay time
4. Increase the capacitance C1 can increase the delay time
5. Possess of input power indicator
6. Possess of relay pull-in indicator
7. can control the AC 220V/10A equipment. (Maximum control device 2000W)
8. Possess of relay freewheeling protection
9. Delay time formula: T=1.1RC. For example: Capacitance 100uf resistance 100K T = 1.1 * 100000 * 0.0001 = 11 seconds
