CR4211S-100

Current Sensors Overview

The CR4211S-100 is a self-powered split-core AC current transducer manufactured by CR Magnetics Inc. It is designed to measure alternating current with a sensing capacity of 100A. The device operates within a frequency range of 50Hz to 400Hz and maintains an accuracy of ±0.5%. It provides a proportional 0-10 VDC output signal representing the average RMS input AC current. The unit supports mounting on 35mm DIN rails or via panel installation, ensuring compatibility with standard industrial control environments.

Current Sensors Feature Summary

• Self-powered operation eliminates the need for external excitation voltage
• Split-core design allows for non-intrusive installation around conductors
• Calibrated to deliver a standardized 0-10 VDC analog output signal

Current Sensors Applications

• Industrial power monitoring systems
• Electrical distribution panels
• Energy management metering equipment

Current Sensors Procurement Notes

Verify that the specific part number matches the required current rating and output signal type before ordering. Confirm that the operating frequency range aligns with the application's electrical parameters. Ensure the physical mounting configuration meets the installation site requirements. Check for any specific environmental ratings if the deployment location involves extreme temperatures or humidity.

Current Sensors Selection Notes

Select this component when a self-powered solution is preferred to simplify wiring. Consider the split-core architecture for retrofits where conductor interruption is not feasible. Evaluate the 0-10 VDC output requirement against the receiving device's input specifications. Assess the 100A current limit to ensure it covers the maximum expected load without saturation.

Current Sensors Part Context

This model belongs to the CR4211 series of AC current transducers from CR Magnetics Inc. The series includes various current ratings and output configurations. The 'S' suffix typically denotes the split-core variant, distinguishing it from solid-core versions. This family is engineered for reliable performance in industrial sensor applications requiring accurate RMS measurement.

Current Sensors Replacement Considerations

Direct substitutes must match the 100A rating, 0-10 VDC output, and split-core form factor. Verify that alternative models support the same 50Hz-400Hz frequency range and ±0.5% accuracy. Ensure mechanical mounting dimensions are compatible with existing 35mm DIN rail or panel setups.
