## Description

Module for non-invasive measurement of AC or DC current, ideal for monitoring consumption without interrupting the circuit. Offers analog output proportional to current and digital output with adjustable threshold for simple triggering, operates at 5V and supports up to ±100A DC or 70A AC. The conductor passes through a 9 mm hole for quick mounting.
The WCS1600-100A Hall Effect Current Sensor Module is ideal for applications that require accurate measurement of DC or AC current without physically breaking the circuit. The module allows non-invasive detection of current through the conductor, providing an easy-to-implement solution for monitoring electrical consumption in various applications.
It has two types of outputs, an analog ( Aout ) proportional to the measured current, and a digital ( Dout ) which is automatically activated when the current exceeds a threshold set by the trimmer. The digital output can be useful when you want to activate a 5V relay for example by sending a signal to it.
Attention: There is an arrow on the sensor indicating the mounting direction of the measured wire. It follows the flow from + to - in the direction of the arrow.
