CR Magnetics, Inc. Monitor - Current/Voltage - Relay Output CR4640-50

The CR4640 series consists of loop-powered AC voltage transmitters designed to provide a 4-20 mA DC output proportional to the average RMS AC voltage input, with input ranges up to 600 VAC. The device is DIN rail or panel mountable, measuring 88.7 mm in length, 36.6 mm in height, and 28.3 mm in depth. It operates with a 24 VDC loop supply, has a 0.5% basic accuracy, and is rated for operation from 0°C to +60°C with a thermal drift of 500 ppm/°C. The transmitter meets IEC 61010-1, UL 61010B-1, and CAN/CSA-C22.2 No. 61010-1-2004 standards, supports an input frequency range of 20 Hz to 400 Hz, and provides 2500 VDC insulation between input and output. The CR4640 is a two-element transmitter intended for single-phase, center-tapped residential applications. For input voltage ranges beyond 500 VAC, external potential transformers are required.
