Fulabs FR120N LR7843 D4184 Isolated MOSFET MOS Tube FET Module Replacement Relay 100V 9.4A 30V 161A 40V 50A Board

Module Features

- Optocoupler Isolation：The control signal is isolated from the power supply of the controlled device, which greatly enhances anti-interference capability.

- Wide Compatibility：Compatible with single-chip microcomputers and Arduino control boards, supporting 3V/5V signal inputs.

- Flexible Control Mode：High-level to start, low-level to stop, with PWM speed regulation function.

- Application Scenarios：Suitable for controlling DC devices such as motor start/stop and solenoid valves.

- Diversified MOSFET Specifications：

- FR120N: 100V/9.4A

- LR7843: 30V/161A

- AOD4184: 40V/50A

- Flexible Signal Input Interface：The signal input side can be welded with terminal blocks or pins, compatible with breadboard circuit building.

- Adaptive Output Interface：Supports welding terminal blocks or direct wire soldering to meet different installation requirements.

- Compact Size Design：Module size is 23mm×16mm, with 2 screw holes of 2mm diameter (hole spacing 8mm) for easy fixing.
