CR4220-15

Current Sensors Overview

The CR4220-15 is a loop-powered AC current transducer manufactured by CR Magnetics Inc. It features a solid core design with a single element configuration, suitable for measuring AC currents within a range of 0 to 15 A. The device operates at frequencies between 50 and 400 Hz and provides a calibrated 4 to 20 mA DC output signal proportional to the average RMS input current. It utilizes transformer conditioning, offers bidirectional polarization, and includes an insulation voltage rating of 2500 VDC. The unit mounts on a DIN rail and has a response time of 250ms.

Current Sensors Procurement Notes

Verify that the specific part number matches the required input current range of 0-15A and frequency specifications of 50-400Hz. Confirm that the application environment supports loop-powered operation and DIN rail mounting. Ensure compatibility with existing PLC power supplies for the output current loop before procurement.

Current Sensors Selection Notes

Select this model when a loop-powered solution is required for AC current monitoring up to 15A. Consider the 2500VDC insulation voltage for safety requirements. Choose based on the need for average RMS measurement accuracy and the availability of a 4-20mA interface for integration with standard control instruments.

Current Sensors Part Context

This component belongs to the CR4220 series of loop-powered AC current transducers from CR Magnetics. The series is designed for remote monitoring of AC sine currents using a 35mm DIN rail or panel mount enclosure. These devices are characterized by low cost, high precision, and simple wiring, interfacing with most commercial instruments via the 4-20mA output.

Current Sensors Replacement Considerations

Cross-reference with other models in the CR4220 series, such as CR4220-10 or CR4220-20, if different current ranges are needed. Verify that substitute parts maintain the same loop-powered architecture and 4-20mA output characteristics.
