CR4220S-25

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 CR4220 Transducers C Features Single Element - .79” Window 0.5 to 50 AAC Input Range Relatively low cost 35mm DIN rail or panel mount High Accuracy Easy wiring Interfaces with most commercially available instrumentation Connection diagram printed on case Regulatory Agencies Recognized to meet UL 61010B-1 Constructed to meet CAN/CSA-C22.2, No. 61010-1-2004 Meets requirement of IEC 61010-1 and BS EN 61010-1 CR4260 Two Element - .26” Window 0.5 to 30 AAC Input Range E199795 All single phase current transducers are available in split core design.
