CR4260-5

Current Sensors Overview

The CR4260-5 is a loop-powered AC current transmitter manufactured by CR Magnetics Inc. It features a solid core design with two sensing elements to monitor average RMS AC input currents within a range of 0 to 5 Amperes. The device generates a calibrated 4 mA DC to 20 mA DC output signal proportional to the input, powered by a user-supplied PLC source within the output loop. It supports frequencies from 20 Hz to 4 kHz and offers an accuracy of ±0.5%. The unit provides 2500 VDC isolation and operates on a 24V supply voltage.

Current Sensors Feature Summary

• Produces a calibrated 4-20 mA DC output signal proportional to the average RMS input AC current
• Utilizes a solid core design with dual sensing elements for robust monitoring
• Features high isolation voltage capability for safe industrial operation
• Offers precise measurement with low error margins for reliable data acquisition

Current Sensors Applications

• Remote current detection in industrial automation systems
• Monitoring motor faults and operational status
• Surveillance of heating element performance
• Detection and control in multi-point current panels

Current Sensors Procurement Notes

Verify that the specific part number matches the required input current range and frequency specifications for your application. Confirm compatibility with the existing PLC power supply voltage and loop resistance limits. Ensure the installation environment meets the thermal and electrical isolation requirements specified in the official datasheet to maintain accuracy and safety standards.

Current Sensors Selection Notes

Select this model when a loop-powered solution is preferred to simplify wiring by eliminating separate power supplies. The dual-element solid core design is suitable for applications requiring high reliability and noise immunity. Consider the 20 Hz to 4 kHz frequency range to ensure it covers the operating spectrum of the monitored AC signals without distortion or loss of precision.

Current Sensors Part Context

This component belongs to the CR4260 series of loop-powered AC current transmitters from CR Magnetics. The series is designed for industrial environments where remote monitoring of AC sine waves is necessary. The CR4260-5 specifically denotes the variant configured for a 5 Ampere input range, distinguishing it from other models in the family with different current capacities.

Current Sensors Replacement Considerations

The CR4220-5 is a comparable single-element alternative within the same product family. When substituting, verify that the change from dual to single element does not impact the required accuracy or fault detection capabilities for the specific application.
