CR Magnetics, Inc. Monitor - Current/Voltage - Relay Output CR4820-50

The CR4820 series is a single-element, DIN rail or panel mount average RMS AC voltage transducer designed to provide a DC output proportional to AC voltage input, with applications in motor, heating, and lighting element monitoring. It operates on 24 Vdc power with a 1.0 to 600 VAC input range and offers a 0-10 VDC output, with outputs isolated from inputs. The device meets UL 61010B-1, CAN/CSA-C22.2 No. 61010-1-2004, IEC 61010-1, and BS EN 61010-1 standards. It has a 0.5% basic accuracy, 500 PPM/°C thermal drift, 250 ms response time, and operates from 0°C to +60°C. The case dimensions are 88.7 mm x 36.6 mm x 76.8 mm, with a weight of 0.5 lbs. The CR4820-50 variant specifies a 0-50 VAC input range, extending the base series capability.
