CR4220-10

Current Sensors Overview

The CR4220-10 is a single-channel transformer-based current sensor module designed for AC sine wave monitoring. It provides a calibrated 4 mA to 20 mA DC output signal proportional to the average RMS input current. The device operates within a frequency range of 50 Hz to 400 Hz and features an accuracy of ±0.5%. It requires a 24 V supply voltage and exhibits a response time of 250 ms. The operating temperature range is specified from 0°C to 60°C.

Current Sensors Procurement Notes

Verify that the specific part number matches the required current rating and output signal type. Confirm supply voltage requirements align with system specifications. Ensure environmental conditions fall within the stated operating temperature range. Check for RoHS compliance status if required by project standards. Validate interface compatibility with existing PLC or monitoring equipment before procurement.

Current Sensors Selection Notes

Select this component when precise monitoring of AC sine wave currents is required in industrial settings. The 10A rating suits moderate current applications. Consider the 50-400Hz frequency range for standard power line or variable frequency drive environments. The loop-powered design simplifies installation by eliminating separate output power supplies. Evaluate space constraints as the module package offers compact integration options.

Current Sensors Part Context

This device belongs to the CR4220 series of AC current transducers manufactured by CR Magnetics Inc. The series includes variants with different current ratings, such as the CR4220-25. These devices are designed for DIN rail or panel mounting, providing cost-effective solutions for current monitoring in control panels and industrial automation systems.

Current Sensors Replacement Considerations

Direct substitutes include other models within the CR4220 series with matching current ratings. Verify that replacement units maintain the same 4-20 mA output configuration and 24V supply requirement. Cross-reference frequency ranges and accuracy specifications to ensure functional equivalence in the target application.
