Specification:
Module chip: NE555 chip
Delay modue: delay connect module
Input voltage: DC 5V
Control voltage: AC 0~250V / max
10A, DC 0~30V / max
10A the operating voltage: 5 volts DC; (otherwise 5V optional)
Max load: 2200W

Applications:
Vehicle equipment-delay to prevent car ignition, prevention of high sudden current to burn components and devices.

Module performance and features:
1.Turn on the power relay and delay the pull-in. Specifically: after supplying 5v power to the relay, the relay will 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 release of the relay 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

Package Included:
10 X NE555 DC 5V delay timer module
