Positive control wiring introduction:
1. Power input terminal:
VCC is connected to the positive voltage, GND is connected to the negative voltage, and S / S is connected to the negative voltage
IN1, IN2 are connected to positive voltage control, IN1 controls terminal, IN2 controls K2 terminal
2. Control device output:
The output terminal is clearly marked with 234, 3 is a common point, 2 is normally open, and 4 is normally closed. K1, K2 means two relays work.
Negative control wiring introduction:
1. Power input terminal:
VCC is connected to the positive voltage, GND is connected to the negative voltage, and S / S is connected to the positive voltage
IN1, IN2 are connected to negative voltage control, IN1 controls terminal, IN2 controls K2 terminal
2. Control device output:
The output terminal is clearly marked with 234, 3 is a common point, 2 is normally open, and 4 is normally closed. , K2 means two relays work.
