CMS-202DR sensors for use with the CMS-600 and CMS-770 current measuring systems up to 40A. The sensors with an installation width of 25mm for universal DIN rail mounting ensure precise and effective measurement. Due to their unique compactness, the CMS sensors are also ideal for retrofitting in existing installations. The sensors measure TRMS, AC and DC currents (current, min/max and hold values) and transmit these values to the control unit via a 4-pin ribbon cable. They comply with DIN EN 61010-1.
