Current Sensors Procurement Notes

Verify the specific output signal type required for your application, as variations exist within the CR4420 series. Confirm that the 500mA detection range aligns with your system's maximum current expectations. Ensure the operating environment remains within the specified 0°C to 60°C temperature limits. Check for compatibility with the 24V DC power supply requirement. Validate that the 50Hz to 400Hz frequency range matches your AC source characteristics.

Current Sensors Selection Notes

Select this component when precise low-current AC measurement is required in industrial settings. The 500mA rating makes it suitable for smaller load monitoring tasks compared to higher-amperage models. Consider the bidirectional feature if reverse current flow needs to be detected. The module form factor simplifies integration into existing DIN rail or panel setups. Ensure the 24V power supply is available and stable for consistent operation.

Current Sensors Part Context

This model belongs to the CR4400 series of RMS AC current transducers from CR Magnetics Inc. The series includes various current ratings and output configurations, such as the CR4420-5 and CR4470-5. These sensors are designed for robust performance in demanding environments, utilizing solid-core transformer technology. The CR4420-0.5 specifically addresses applications requiring sensitive detection of sub-ampere AC currents.

Current Sensors Replacement Considerations

Direct substitutes include other models within the CR4420 series with different current ratings, such as CR4420-5 or CR4420-10, if the detection range can be adjusted. Verify that any replacement maintains the same 24V power requirement and module form factor. Ensure the replacement supports bidirectional operation and compatible frequency ranges.
