ShillehTek WCS1700 70A Hall Current Sensor Module Overcurrent Detect

The WCS1700 is a Hall-effect current sensor module designed to monitor heavy electrical loads safely up to 70A. It measures AC or DC currents via a non-contact magnetic induction method so the sensing conductor passes through the sensor hole and your controller remains galvanically isolated from the high-power circuit. An on-board protection circuit asserts a digital fault signal when a user-set trip point is exceeded, effectively acting as a smart electronic fuse for motors and power supplies. A potentiometer lets you dial in a specific Overcurrent Threshold, while dual outputs provide an Analog Output (Aout) for real-time logging and a Digital Output (Dout) for immediate fault detection; an onboard LED indicates overcurrent status for easier debugging.
