CR5220-20

Current Sensors Overview

The CR5220-20 is a DC current transducer manufactured by CR Magnetics Inc. It utilizes a magnetic modulator, closed-loop Hall effect sensor technology to measure direct current. The device features a solid core design with a single sensing element. It accepts an input current range of 0 to 20 A DC and provides a ratiometric analog output signal ranging from 4 mA to 20 mA. The unit operates on a 24 VDC power supply with a tolerance of +/-10% and has a maximum current supply consumption of 100 mA. It supports mounting via DIN rail or panel installation.

Current Sensors Feature Summary

• Closed-loop magnetic modulator technology for accurate DC current measurement
• Solid core design eliminating the need for split-core installation
• Ratiometric 4-20 mA analog output signal for industrial integration

Current Sensors Applications

• Industrial process control systems requiring precise DC current monitoring
• Power supply equipment and electrical distribution panels
• Battery management and charging station infrastructure

Current Sensors Procurement Notes

Verify that the specific part number CR5220-20 matches the required 20A input range and 4-20mA output configuration. Confirm the package type aligns with your DIN rail or panel mounting requirements. Ensure the 24VDC supply voltage specification is compatible with your system's power architecture before procurement.

Current Sensors Selection Notes

Select this component when a robust, isolated measurement of high-current DC applications is required. The closed-loop design offers superior linearity and bandwidth compared to open-loop alternatives. Consider the 20A limit and 4-20mA standard interface compatibility with existing PLC or SCADA systems during the selection phase.

Current Sensors Part Context

This model belongs to the CR5220 series of current transducers from CR Magnetics. The series includes variants such as the CR5220-30, which shares similar architectural features but differs in current rating. These devices are designed for industrial environments where reliable, long-term DC current monitoring is critical for system safety and efficiency.

Current Sensors Replacement Considerations

Direct substitutes within the same family include the CR5220-30, though it supports a different current range. Cross-manufacturer replacements must match the 4-20mA output, 24V supply, and closed-loop Hall effect technology to ensure functional compatibility without circuit redesign.
