Self Powered AC Current Transducer
DIN RAIL / PANEL MOUNT, AVERAGE RMS
The
CR4210
and
CR4211
Series Current Transducers
are self powered. These transducers are calibrated to
provide a 0-5 VDC and 0-10 VDC signal that is
proportional to the average RMS input AC current.
Designed for multi-point current sensing, these devices
provide excellent features in a high value package.
Applications
Multi-point current sensing and control panels
Remote current sensing
Monitor motor faults
Monitor heating elements
Monitor lighting elements
