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 KI 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 KI 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. KI, K2 means two relays work.
