Product Description

The CR4220 Series, Loop-powered Current Transmitter produces a calibrated 4-20mAdc output signal that is proportional to the Average RMS input AC current. These devices provide long range monitoring of AC sinusoidal currents in an easy to install package. The output signal is generated from a user supplied PLC power supply within the output current loop.
