This is a PWM MOS driver, which based on a MOSFET and Optocoupler, with low inner resistance, can through bigger current. With this module, you can control DC motor, mini DC pump, LED lamp strings, and so on with PWM.
1. DC+: device DC power positive
2. DC-: device DC power negative
3. PWM: signal input port (connects MCU IO ports, PLC interface, DC power)
4. GND: signal negative port
5. OUT+: output port positive (connects device positive)
6. OUT-: output port negative (connects device negative)
