CR4420S-50

Current Sensors Overview

The CR4420S-50 is a split-core current transducer manufactured by CR Magnetics Inc. It features a transformer with conditioning circuitry and provides a bidirectional analog output of 4 to 20 mA DC. The device has a sensitivity range of 50A AC and operates with a response time of 250ms. It requires a 24V DC supply voltage and supports frequency inputs from 20Hz to 5kHz. The unit is housed in a DIN rail mount enclosure, designed for integration into industrial monitoring systems requiring precise current measurement.

Current Sensors Feature Summary

• Provides a standardized 4-20 mA DC analog output signal for easy integration with PLCs and data acquisition systems.
• Utilizes a split-core design allowing installation around existing conductors without breaking the primary circuit.
• Features internal conditioning circuitry to ensure high precision and stable performance across the operating frequency range.

Current Sensors Applications

• Industrial motor control and protection circuits
• Power distribution monitoring systems
• Energy management and metering applications

Current Sensors Procurement Notes

Verify that the required current rating matches the 50A specification for your application. Confirm compatibility with the 24V DC supply voltage and 4-20mA output interface. Ensure the physical dimensions fit the DIN rail mounting location. Check for any specific environmental ratings if used in harsh conditions.

Current Sensors Selection Notes

Select this model when a non-invasive current measurement solution is required for AC currents up to 50A. Consider the 250ms response time for dynamic load monitoring. The bidirectional capability allows for measuring both positive and negative current flow. Verify that the 20Hz to 5kHz frequency range covers the operational spectrum of the monitored equipment.

Current Sensors Part Context

This component belongs to the CR4400 series of current sensors from CR Magnetics Inc. The series includes various models with different current ratings and output configurations. The CR4420S-50 specifically denotes the 50A rating within the split-core, 4-20mA output variant. It is part of a modular system designed for industrial automation and power monitoring.

Current Sensors Replacement Considerations

Direct substitutes include other CR Magnetics models within the CR4400 series with matching 50A ratings and 4-20mA outputs, such as the CR4410S-50 or CR4420S-25, provided the physical mounting and electrical interfaces are compatible. Always verify datasheet specifications before substitution.
