• Bidirectional sensing with a single-element split-core design for easy installation
• High precision accuracy of ±0.5% across the specified frequency range
• Integrated connection diagram printed on the case for simplified wiring

Current Sensors Applications

• Phase-fired controlled heaters
• Quickly varying motor loads
• Chopped waveform drivers
• Harmonic current monitoring

Current Sensors Procurement Notes

Verify that the specific order matches the CR4111-0.5 designation to ensure the correct 0.5A input range and 0-10V output configuration. Confirm that the application environment remains within the specified 0°C to 60°C operating temperature limits. Ensure the power supply provides stable 24V DC without exceeding the 25mA maximum consumption. Check for compliance with UL 61010B-1 and IEC 61010-1 standards if required by local regulations.

Current Sensors Selection Notes

Select this model when measuring AC currents up to 500mA with high accuracy requirements. Choose the CR4111-0.5 over standard transducers when dealing with distorted waveforms due to its True RMS functionality. Consider the 0-10V output option if voltage signaling is preferred over current loops. Ensure the physical window size accommodates the conductor diameter, as this model utilizes a single-element core design.

Current Sensors Part Context

This component belongs to the CR4100 series of True RMS Current Transducers manufactured by CR Magnetics Inc. The series includes various models with different input ranges and output types, all sharing common features like 24VDC power and DIN rail compatibility. The CR4111-0.5 specifically addresses low-current applications requiring precise RMS values in industrial settings.

Current Sensors Replacement Considerations

For direct replacement, verify the CR4111S-0.5 if a split-core variant is needed, noting it may lack UL recognition. Cross-reference the CR4110-0.5 if a fixed-core design is acceptable. Ensure any substitute maintains the 0-10V output and 24VDC power requirements to fit existing system architecture.
