Average RMS AC Current Transducer
DIN RAIL / PANEL MOUNT, AVERAGE RMS
The
CR4400
Series, Current Transducers and Transmitters are
designed to produce a DC output 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 .
Applications
Multi-point current sensing and control panels
Monitor motor faults
Monitor heating elements
Monitor lighting elements
