HALJIA 5PCS LR784 LR7843 MOS Module MOSFET Control Field Effect Isolation MOSFET/MOS Tube FET Replacement Relay

Module: LR784/LR7843; Voltage:30V 161A With optocoupler isolation, the control signal is isolated from the power supply of the controlled device, which greatly improves the interference. Compatible with single chip and control board, 3 V or 5 V signal. High level start, low level stop, PWM speed. Widely used to control engine start and stop, solenoid valve and other tributary equipment. The signal input end can solder the terminal block or pin, compatible with breadboard. The output end can be soldered terminals or directly soldered wires.
