CR4160-25

Current Sensors Overview

The CR4160-25 is a True RMS AC current transducer from the CR4100 series, designed for precise measurement in phase-fired control systems. It features a dual-element split-core design with a 0.26-inch window, supporting an input range of 0.5 to 30 AAC. The device operates on 24 VDC power and provides a 4-20 mA DC output signal. Key electrical parameters include a frequency range of 20 Hz to 5 kHz, ±0.5% accuracy, and a response time of 250 ms. It is constructed to meet CAN/CSA-C22.2 standards and supports bidirectional current detection.

Current Sensors Feature Summary

• True RMS measurement capability ensures accurate readings for chopped waves and phase-fired control applications
• Dual-element split-core construction allows for easy installation without breaking the conductor
• Integrated conditioning transformer provides stable 4-20 mA output signal
• Bidirectional sensing capability supports complex motor load monitoring

Current Sensors Applications

• Phase-fired controlled heater systems
• Quickly varying motor loads
• Industrial power monitoring where high accuracy is required

Current Sensors Procurement Notes

Verify that the specific part number matches the required input range and output configuration. Confirm that the dual-element split-core design fits the conductor size within the 0.26-inch window. Ensure the application environment falls within the specified operating temperature range of 0°C to 60°C. Check for compliance with UL 61010B-1 and CAN/CSA-C22.2 standards if regulatory recognition is mandatory for your installation.

Current Sensors Selection Notes

Select this model when True RMS accuracy is critical for non-sinusoidal waveforms typical in phase-controlled heating or variable speed drives. The dual-element design offers higher precision than single-element alternatives. Consider the 4-20 mA output compatibility with existing PLC or SCADA systems. Verify that the 24 VDC supply voltage aligns with available plant power infrastructure before finalizing the selection.

Current Sensors Part Context

This component belongs to the CR4100 series of True RMS Current Transducers and Transmitters by CR Magnetics. The series includes single, dual, and triple-element variants with various input ranges. The CR4160-25 specifically utilizes the dual-element architecture, distinguishing it from the single-element CR4110/CR4120 models and the triple-element CR4170/CR4180 models within the same product family.

Current Sensors Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Users should verify compatibility with existing mounting rails (35mm DIN Rail) and wiring configurations when considering alternative models from the same manufacturer.
