MOSFET Field Effect Transistor Module Optocoupler Isolation Alternative Relay (MULTI)

Features: 
- With optocoupler isolation, the control signal and the power of the controlled device are isolated, and greatly improve the anti-jamming
- Compatible with MCU, Arduino light control board, 3V or 5V signal, supports high-level start, low-level stop, PWM speed can be controlled
- The signal input side can be soldered to the terminal or pin itself, compatible with the breadboard, the output can be welded terminals or direct wired
- Widely used to control the motor start and stop, solenoid valves and other tributary devices
