CR4220S-100

Current Sensors Overview

The CR4220S-100 is a single-channel AC current transducer from the CR Magnetics series, designed for average RMS measurement. It features a split-core design with a 100A input range and provides a calibrated 4mA to 20mA DC output proportional to the input current. The device operates on a 24V supply with a maximum current consumption of 35mA. It supports installation via DIN rail or panel mounting and functions within a temperature range of 0°C to 60°C.

Current Sensors Feature Summary

• Provides remote monitoring of AC sine currents through a loop-powered 4-20mA output signal
• Features a split-core design for easy installation without breaking the primary circuit
• Offers high accuracy suitable for interfacing with most commercially available instrumentation

Current Sensors Applications

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

Current Sensors Procurement Notes

Verify that the specific suffix 'S' confirms the split-core configuration required for your application, as standard versions may differ. Confirm the 4-20mA output matches your PLC or monitoring system input requirements. Ensure the 24VDC power supply aligns with your existing infrastructure. Check for RoHS compliance status if environmental regulations apply to your project specifications.

Current Sensors Selection Notes

Select this model when precise average RMS measurement of AC currents up to 100A is required in space-constrained environments. The split-core design facilitates retrofitting into existing electrical panels without disconnecting conductors. Choose this over closed-loop Hall effect sensors if cost-effectiveness and simplicity are prioritized over DC measurement capabilities or higher frequency response.

Current Sensors Part Context

This component belongs to the CR4220/CR4260 series of loop-powered AC current transducers. These devices are engineered for value-oriented applications requiring reliable current monitoring. The series emphasizes ease of installation and compatibility with standard industrial control equipment, serving as a robust solution for basic AC current sensing tasks in commercial and industrial settings.

Current Sensors Replacement Considerations

The CR4220S-50 serves as a substitute for lower current ranges (5A). For non-split-core requirements, the CR4220-100 is the equivalent solid-core variant. Higher precision needs may require the CR4100 series True RMS transducers.
