CR4120-0.5

Current Sensors Overview

The CR4120-0.5 is a current transducer designed for AC current measurement with a range of 0 to 0.5A AC. It operates on a 24V supply voltage and draws a maximum supply current of 40mA. The device features a response time of 250ms and maintains an accuracy of ±0.5%. It supports bidirectional polarization and functions within an operating temperature range of 0°C to 60°C. The sensor covers an operating frequency band from 20Hz to 5kHz, ensuring reliable monitoring across typical industrial frequencies.

Current Sensors Feature Summary

• Bidirectional current sensing capability for accurate measurement in both directions
• High precision with consistent ±0.5% accuracy across the specified frequency range
• Integrated conditioning for direct signal output without external processing

Current Sensors Applications

• Industrial power monitoring systems requiring precise low-current measurement
• AC circuit protection devices needing fast response times
• Energy management equipment tracking small load variations

Current Sensors Procurement Notes

Verify the specific ordering suffix and package configuration against the manufacturer's official datasheet before purchase. Confirm that the supply voltage requirements match your system design. Ensure the operating temperature range meets your environmental conditions. Check for any specific mounting or wiring requirements detailed in the installation guide to guarantee proper integration and performance.

Current Sensors Selection Notes

Select this model when measuring AC currents up to 0.5A with high accuracy is required. Consider the bidirectional nature if current flow direction varies. Evaluate the 24V supply requirement against available power rails. The 250ms response time may be insufficient for very high-speed transient applications; verify timing needs against the 20Hz-5kHz frequency range.

Current Sensors Part Context

This component belongs to the CR Magnetics current sensor family, which includes various models like the CR4120-100 and CR4120S-20. These sensors typically offer transformer-based isolation with integrated signal conditioning. The series is designed for industrial applications requiring reliable AC current monitoring with standardized supply voltages and accuracy specifications.

Current Sensors Replacement Considerations

The CR4120-100 offers similar characteristics but with a higher current rating of 100A. For lower current ranges, check other models in the CR4120 series. Ensure replacement parts maintain the same 24V supply and ±0.5% accuracy requirements. Verify compatibility with existing mounting and wiring configurations.
