CR4220-5

Current Sensors Overview

The CR4220-5 is a loop-powered AC current transducer by CR Magnetics Inc. It features a single channel with a 5A input rating and provides a ratiometric 4mA to 20mA DC output proportional to the average RMS input current. The device operates within a frequency range of 50Hz to 400Hz and maintains an accuracy of ±0.5%. Designed for bidirectional measurement, it utilizes a transformer-based sensing element with conditioning circuitry. The unit supports 35mm DIN rail or panel mounting and requires a user-provided PLC power source for the output loop.
