Specifications:
Voltage: 5V DC
Quiescent current: 8mA
Operating current: 95mA
Trigger: passive switch trigger, response time is 0.03 seconds (the trigger terminal can not access the active signal)
Minimum on-off time: 0.2 seconds
Load capacity: 10A
Output form: normally open + normally closed
Size: 70*20*19mm
Features:
- Using industrial-grade single-chip microcomputer to control time, high precision and stable performance;
- Two adjustable resistors are used to adjust the time, and the connection duration and the disconnection time can be independently adjusted;
- The external contact is activated, and the timing is started by shorting the self-reset button. It is also possible to start the countdown by shorting the triggers together to achieve power-on;
- The time range is divided into 0-100 seconds.
Basic working principle:
Taking the factory standard setting as an example, the red LED will light when the power is turned on, and the relay is in the off state. When shorted at the trigger end, the module green light is on and immediately enters the working state. Triggering again in the working state will stop working.
In the working state, the relay will pass T1 seconds, break T2 seconds, pass T1 seconds, break T2 seconds... infinite loop. T1 T2 is the length of time the user adjusts with an adjustable resistor.
Instructions:
- Power access:
The module is connected to the power supply according to the correct power supply voltage and polarity. The red line of the power supply terminal is positive and the black line is negative.
- Trigger line access:
