1. With optocoupler isolation, the control signal and the power of the controlled device are isolated, which greatly increases the rigidity of the interference.
2. Compatible with MCU and Arduino control board, 3V or 5V signal
3. High level start, low level stop, PWM speed regulation
4 .Widely used to control the start and stop of the motor, solenoid valve and other tributary equipment
5. There are various specifications of MOS tube to provide choices,
