CR4160-30

Current Sensors Overview

The CR4160-30 is a two-element True RMS current transducer manufactured by CR Magnetics, designed for precise AC measurement. It features a split-core design with a 0.26-inch window and supports an input range of 0.5 to 30 AAC. The device provides a proportional 4mA to 20mA output signal and operates on a 24V DC power supply with a maximum current draw of 70mA. It offers ±0.5% accuracy within a frequency range of 20Hz to 5kHz and has a response time of 250ms. The unit is polarized bidirectionally and can be mounted on a 35mm DIN rail or panel.

Current Sensors Feature Summary

• True RMS measurement capability ensures accurate readings for chopped wave and phase-fired control systems
• Split-core construction allows for non-invasive installation around conductors
• Dual mounting options support both standard DIN rail and direct panel installation

Current Sensors Applications

• Phase fired controlled heaters
• Quickly varying motor loads
• Industrial process monitoring requiring high precision AC current data

Current Sensors Procurement Notes

Verify the specific model suffix against official documentation to confirm the exact input range and output configuration. Ensure that the required conductor size fits within the specified 0.26-inch window aperture. Confirm that the application environment remains within the stated operating temperature limits and that the 24V DC power supply meets the maximum current consumption requirements for reliable operation.

Current Sensors Selection Notes

Select this component when high-precision AC current monitoring is required in environments with complex waveforms. The True RMS technology distinguishes it from average-responding devices, making it suitable for phase-fired applications. Consider the split-core design for retrofitting existing installations without breaking the primary circuit. Verify compatibility with downstream PLCs or controllers accepting 4-20mA signals.

Current Sensors Part Context

This part belongs to the CR4100 Series of True RMS Current Transducers and Transmitters. The series is engineered for applications demanding higher accuracy than standard transducers. The CR4160 specifically denotes a two-element configuration with a split-core design, differentiating it from single-element solid-core variants like the CR4110 or three-element models.
