Loop-Powered AC Current Transmitter
DIN RAIL / PANEL MOUNT, AVERAGE RMS
The
CR4200
Series, Current Transmitters produce a calibrated
4-20 mADC signal that is proportional to the average RMS
input AC current. Designed for multi-point current sensing,
these devices provide excellent features in a value package.
The output signal is generated from a user supplied 24 VDC
power supply within the output current loop.
Applications
Multi-point current sensing and control panels
Remote current sensing
Monitor motor faults
Monitor heating elements
Monitor lighting elements
