4-Channel IRF540 MOSFET Switch Module

4-Channel IRF540 MOSFET Switch Module delivers powerful multi-channel DC switching capabilities for microcontrollers, Arduino, Raspberry Pi, and industrial PLC control setups. Featuring four independent high-current N-channel IRF540 power MOSFETs paired with onboard optocoupler isolation, this board allows low-voltage logic circuits (3.3V to 5V) to switch and PWM-dim high-current DC loads up to 100V without electrical noise interference. Consequently, developers and roboticists can seamlessly control heavy DC motors, solenoid valves, high-power LED arrays, and heating coils with ultra-fast switching response. Furthermore, individual screw terminal blocks make wiring clean and reliable during prototype testing and field installation.

Key Features:

• 4 Independent Switching Channels: Controls up to four separate high-power DC loads concurrently from digital microcontroller GPIO pins.
• Optical Isolation Protection: Onboard optocouplers isolate sensitive logic microcontrollers from inductive voltage spikes and motor back-EMF.
• PWM Speed & Dimming Control: Supports high-frequency Pulse Width Modulation for smooth DC motor speed adjustment and LED brightness regulation.
• High Voltage Handling: N-Channel IRF540 MOSFETs support switched load rails from 0V up to 100V DC.
• Heavy-Duty Terminal Blocks: High-current screw terminals provide secure, low-resistance connections for heavy power wiring.
