Overview

This module is mainly used to implement level conversion and power amplification functions, to adapt low-level signals (such as PWM output of microcontrollers or microcontrollers) to drive high-power devices (such as relays or motors). Suitable for industrial control, motor drive, relay control and other scenarios that require low-level signals to drive high-power equipment, especially for applications that require high reliability.

Can be used to drive motors, fans, water pumps, electromagnetic locks, etc

Main Features and Functions

• Electrical isolation: By using optocouplers (U13) to achieve electrical isolation between input and output, the system's anti-interference ability is improved.

• Power amplification: PWM signal amplified by MOSFET (Q2), suitable for driving high-power loads.

• High reliability: The protection mechanisms of D29 and C30, as well as a reasonable resistor current limiting network, improve the stability of the circuit.

Module Parameters

• Power supply voltage: 5~12V

• Connection method: 3Pin PH2.0 anti reverse connection

• Module size: 30.4 * 22.4mm

• Installation method: M3 screw compatible with Lego socket
