Feature

●Put on the power relay and delay suction. Specifically: after supplying 12V power supply to relay, relay will not absorb immediately. The state of output terminal of relay is: normally open and public disconnect, normally closed and public conduction; when the delay is 1-10S (adjustable), the relay sucks.
●At this time, the state of output terminal of relay is: normally open and public conduction, often closed and public disconnection;
●As long as the module is continuously powered, this state will be maintained. Hold.

Description

Description:

1. Adjustable delay time, (0-10 seconds)

2. Increasing potentiometer can increase delay time

3. Increasing capacitance C1 can increase delay time

4. Indicator lamp with input power supply

5. Suction indicator with relay

6. Controllable 220V/10A AC equipment. (Maximum Control Equipment 2000W)

7. It has relay continuous current protection.

8. Delay time formula: T = 1.1RC. For example: capacitance 100uF resistance 100KT = 1.1 * 100000 * 0.0001 = 11 seconds
