CR4111S-30

Current Sensors Overview

The CR4111S-30 is a True RMS AC split core current transducer manufactured by CR Magnetics Inc. It features a 30A detection range and a single channel output via RS485 interface. The device operates on a 24V supply with a maximum current consumption of 30mA. It supports bidirectional measurement within a frequency range of 20Hz to 5kHz. Key performance metrics include ±0.5% accuracy, 250ms response time, and operation between 0°C and 60°C. The module design allows for DIN rail or panel mounting.

Current Sensors Feature Summary

• True RMS measurement capability for non-sinusoidal waveforms
• Split core design for easy installation without circuit interruption
• RS485 digital communication interface
• Bidirectional current sensing

Current Sensors Applications

• Chopped wave control systems
• Phase-fired control applications
• Power monitoring in industrial automation
• Energy management systems requiring accurate RMS data

Current Sensors Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required communication protocols and mounting configurations. Confirm that the 24V DC supply voltage aligns with existing system infrastructure. Check for RoHS compliance status if environmental regulations apply to the deployment environment. Ensure the split core aperture matches the conductor size being monitored.

Current Sensors Selection Notes

Select this model when precise RMS values are required for distorted AC waveforms rather than average-responding sensors. The RS485 output facilitates integration into digital monitoring networks. Consider the 30A rating relative to peak load requirements. The split core form factor simplifies retrofitting into existing electrical panels compared to solid-core alternatives.

Current Sensors Part Context

This component belongs to the CR4111S series of True RMS AC split core current transducers from CR Magnetics Inc. The series is engineered for applications involving complex AC current waveforms. It provides high-accuracy measurement suitable for modern power quality analysis. The module format ensures standardized installation across various industrial enclosures.

Current Sensors Replacement Considerations

Direct substitutes within the same series include models with different current ratings such as CR4111S-15 or CR4111S-75. Verify that alternative part numbers maintain the same RS485 output and True RMS functionality. Cross-model generic features do not guarantee identical performance characteristics.
