CR Magnetics, Inc. Monitor - Current/Voltage - Relay Output CR4870-500

The CR4870 is a three-element, four-wire AC voltage transducer designed to provide a 0 to 5 VDC output proportional to RMS AC voltage input, suitable for monitoring applications such as motor, heating, and lighting element fault detection. It mounts on 35 mm DIN rail or panel, operates from a 24 Vdc supply, and accepts input ranges from 1.0 to 600 VAC, with the -500 suffix indicating a 0-500 VAC range. The output is isolated from the input, with basic accuracy of 0.5% and response time of 250 ms. It meets UL 61010B-1, CAN/CSA-C22.2 No. 61010-1-2004, IEC 61010-1, and BS EN 61010-1 standards. Dimensions are 88.7 mm length, 36.6 mm height, and 28.3 mm depth, with a weight of 0.5 lbs. Operating temperature ranges from 0°C to +60°C, and insulation voltage is 2500 Vdc.
