Connects to a DC5V (3.3V) power supply for reliable operation. Supports control of high-power DC devices such as motors, light bulbs, and LED light strips. PWM input allows for precise control of motor speed and light brightness. Indicator light included in the 5V version to signal active status. IN1-IN6 connects to microcontroller or PLC IO ports; remaining features include load side power supply and load terminal connections. 1 VCC: Connect the positive pole of the DC5v (3.3v) power supply. 2 GND: Connect the negative pole of the DC5v (3.3v) power supply, which needs to be grounded together with the signal terminal. 4. H/L jumper: H is high level, L is low level, and the middle is the common terminal. 5 VIN: Load side power supply DC positive level. 6. Connect the load terminals OUT1-OUT6 to the positive pole of the load device, and connect the load terminal GND to the negative pole of the load device.
