CR4110-100

Current Sensors Overview

The CR4110-100 is a True RMS AC current transducer from the CR4100 series, designed for precise measurement of non-sinusoidal waveforms. It features a single-element solid core design with a 0.79-inch window and supports an input range of 0 to 100 AAC. The device operates on a 24 VDC power supply (±10%) and provides a 0 to 5 VDC output signal. It functions within a frequency range of 20 Hz to 5 kHz and maintains an accuracy of ±0.5%. The unit is rated for insulation voltages up to 2500 VDC and operates at altitudes up to 2000 meters.

Current Sensors Feature Summary

• True RMS measurement capability ensures accurate readings for chopped waves and phase-fired control systems
• Single-element solid core construction eliminates the need for air gaps in installation
• Bidirectional module design allows for detection of current flow in both directions
• Integrated conditioning circuitry simplifies integration into monitoring systems

Current Sensors Applications

• Phase-fired controlled heating systems
• Quickly varying motor load monitoring
• Industrial power quality analysis
• Non-sinusoidal AC current waveform measurement

Current Sensors Procurement Notes

Verify that the specific part number matches the required input range and output signal configuration. Confirm that the application environment stays within the specified operating temperature range of 0°C to +60°C. Ensure the primary conductor fits within the 0.79-inch solid core window. Check that the system voltage does not exceed the 2500 VDC insulation rating. Validate that the load impedance meets the minimum requirement of 2K ohms for proper signal transmission.

Current Sensors Selection Notes

Select this model when high precision is required for distorted AC waveforms rather than standard sinusoidal currents. Choose the solid core version if split-core accessibility is not needed during installation. Consider the 0-5 VDC output compatibility with existing PLC or data acquisition inputs. Evaluate the 20 Hz to 5 kHz frequency response against the specific harmonic content of the target application.

Current Sensors Part Context

This component belongs to the CR4100 series of True RMS current transducers manufactured by CR Magnetics Inc. The series includes variants with different input ranges and element counts, such as the two-element CR4160 models. The CR4110 series specifically utilizes a single-element design, offering a balance between cost and performance for standard industrial applications requiring accurate RMS calculations.

Current Sensors Replacement Considerations

Direct replacements must match the True RMS specification and single-element solid core architecture. Verify that alternative sensors support the same 0-100 AAC input range and 0-5 VDC output. Ensure compatible mounting options, such as DIN rail or panel mount configurations. Confirm that the replacement device meets the same UL 61010B-1 safety standards.
