CR4320-5

Current Sensors Overview

The CR Magnetics CR4320-5 is a loop-powered, two-wire AC current transmitter designed for industrial instrumentation. It accepts an input range of 0 to 5 Amperes AC and provides a calibrated 4-20 mA DC output signal directly proportional to the average RMS value of the primary current. The device operates on a 24 VDC supply and features bidirectional measurement capabilities with conditioning modules. This component facilitates accurate current monitoring in electrical systems by converting high-amplitude AC inputs into standardized low-level DC signals suitable for data acquisition and control applications.

Current Sensors Feature Summary

• Loop-powered two-wire design eliminates need for separate power supply
• Provides calibrated 4-20 mA DC output proportional to RMS current
• Bidirectional measurement capability with integrated conditioning

Current Sensors Applications

• Industrial process control systems requiring current monitoring
• Energy management and power distribution instrumentation
• Automated building management system sensor integration

Current Sensors Procurement Notes

Verify that the specific part number matches the required 5 Ampere input range and 4-20 mA output specification. Confirm compatibility with existing 24 VDC loop power supplies and ensure the bidirectional functionality aligns with system requirements. Check for any ordering suffixes that may indicate different calibration or housing options. Validate that the unit is new or surplus from authorized sources to guarantee performance integrity.

Current Sensors Selection Notes

Select this model when a compact, loop-powered solution is needed for measuring AC currents up to 5 Amperes. It is appropriate for applications where space constraints limit the use of larger transducers. Ensure the application requires bidirectional measurement if current flow direction matters. Compare against higher-capacity models like the CR4320-50 if input currents exceed 5 Amperes. Verify that the 4-20 mA output interface matches the receiving equipment's input specifications.

Current Sensors Part Context

The CR4320 series represents CR Magnetics' line of AC current transmitters designed for cost-effective energy monitoring. These devices integrate transformer sensing with electronic conditioning to deliver precise measurements. The CR4320-5 specifically addresses low-current applications within this family, offering a balance between accuracy and simplicity. It complements other sensors in the product portfolio for comprehensive electrical system analysis.

Current Sensors Replacement Considerations

Public confirmed substitute part numbers are not available in verified documentation. When replacing, ensure the new unit matches the 0-5 A input range, 4-20 mA output, and 24 VDC operating voltage. Verify physical mounting dimensions and terminal configurations for compatibility with existing installations.
