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.
