Product Description:

Size: 6.8 CM*2.1 CM;

The main chip: NE555;

Working voltage: DC12V.

Features:

1.The relay time delay and power supply is connected. Specific as follows: for 12 v 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);

3.IKncreasing the potentiometer can increase the delay time;

4.the capacitor C1 can increase delay time;

5.with input power light;

6.A relay and indicator lights;

7.Controlled ac 220V / 10A device.(maximum control equipment 2000 w);

8.Stream with relay protection;

9.The delay time formula: T = 1.1 RC.For example: 100 uf capacitance resistance 100 k T = 1.1*100000*0.0001 = 11 seconds.

 

Applicable Occasions:

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.
