CR4260-20

Current Sensors Overview

The CR4260-20 is a loop-powered AC current transmitter from CR Magnetics Inc. designed for remote monitoring of AC sine currents. It generates a calibrated 4 mA DC to 20 mA DC output signal proportional to the average RMS input AC current. The device operates within a frequency range of 50 Hz to 400 Hz and supports an input range of 0 A to 20 A AC. It features an accuracy of ±0.5% and a response time of 250 ms. The unit requires a 24 V supply voltage derived from the output current loop, typically provided by a PLC power source. Operating temperatures range from 0°C to 60°C.
