CR4220-30

Current Sensors Overview

The CR4220-30 is a loop-powered AC current transducer designed for monitoring average RMS input AC currents. It features a solid core, single-element construction suitable for frequencies between 50Hz and 400Hz. The device provides a calibrated 4mA to 20mA DC output signal proportional to the input current. Key electrical specifications include an input range of 0-30A AC, supply voltage of 24V, accuracy of ±0.5%, and a response time of 250ms.

Current Sensors Feature Summary

• Loop-powered operation utilizing user-provided PLC power within the output current loop
• Calibrated ratiometric output signal proportional to average RMS input AC current
• Solid core design with single element configuration for remote monitoring applications

Current Sensors Applications

• Multi-point current detection and control panels
• Remote current detection systems
• Motor fault monitoring
• Heating element monitoring
• Lighting element monitoring

Current Sensors Procurement Notes

Verify that the specific part number matches the required input range of 0-30A AC. Confirm compatibility with the 50Hz to 400Hz frequency range of the application. Ensure the installation environment supports the DIN rail or panel mounting options provided by the manufacturer. Check for any specific environmental ratings if used in harsh conditions.

Current Sensors Selection Notes

Select this model when a loop-powered solution is required for AC current monitoring without external power supplies for the sensor itself. The 0-30A input range suits moderate current applications. Consider the ±0.5% accuracy requirement against system tolerance needs. The solid core design eliminates the need for breaking conductors during installation.

Current Sensors Part Context

This component belongs to the CR Magnetics CR4220 series of AC current transducers. The series offers various input ranges, such as 0.5A, 5A, and 20A, while maintaining consistent output characteristics and mounting styles. The CR4220-30 specifically addresses higher current measurement needs within this product line.

Current Sensors Replacement Considerations

Direct substitutes may include other models from the CR4220 series with different input ranges, such as CR4220-20 or CR4220-5, if the current rating allows. Verify that alternative parts maintain the same 4-20mA output and loop-powered functionality.
