Specification:
Main chip: NE555
Delay modue: delay connect module
Working voltage: DC 12V
Adjustable delay time (0 ~ 10 seconds)
Counter clockwise adjustment of potentiometer to increase delay time.
Control voltage: AC 0~250V/max. 10A, DC 0~30V/max.10A
Max load: 2200W
Module size: 68 x 21 x 18 mm/ 2.67 x 0.86 x 0.7 inchs
Over-temperature protection: automatically shut down the output after over-temperature

Applications:
Vehicle equipment delays prevent car ignition and prevent sudden high currents from burning components and devices.

Module performance and features:

1.Turn on the power and the relay will delayed pull-in(This module only has a delayed pull-in function and no delayed disconnect function unless the power is off):
For detail: after supplying 12v power , 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 include:
2 x NE555 Delay Timer Relay Module Switch
