CR5220-2

Current Sensors Overview

The CR5220-2 is a DC current transducer manufactured by CR Magnetics Inc. It utilizes a magnetic modulator closed-loop sensor type for accurate measurement. The device operates with a 24V supply voltage and accepts an input current range of 0 to 2A DC. It provides a ratiometric output signal ranging from 4mA to 20mA. Key electrical specifications include a maximum supply current of 100mA, a response time of 250ms, and unidirectional polarization. The unit is designed for operation within a temperature range of 0°C to 50°C.

Current Sensors Feature Summary

• Employs magnetic modulator closed-loop technology for precise DC current sensing
• Provides standard 4mA to 20mA ratiometric output signal
• Supports solid core installation methods including DIN rail and panel mounting

Current Sensors Applications

• DC current monitoring in industrial control systems
• Power supply feedback loops
• Battery management system current tracking

Current Sensors Procurement Notes

Verify that the required input current range matches the 0-2A specification of the CR5220-2. Confirm compatibility with the 24V DC supply voltage and ensure the application environment stays within the 0°C to 50°C operating temperature limits. Check that the 4-20mA output load requirements are met by the receiving equipment.

Current Sensors Selection Notes

Select this component when a unidirectional DC current measurement up to 2A is required. The closed-loop design offers high accuracy compared to open-loop alternatives. Ensure the physical mounting constraints allow for DIN rail or panel installation. Consider the 250ms response time if fast transient detection is critical for the specific application.

Current Sensors Part Context

This part belongs to the CR5200 series of current sensors from CR Magnetics Inc. The series includes variants with different current ratings, such as the CR5220-5 which supports 5A inputs. All units in this family share similar magnetic modulator closed-loop architectures and standardized output signals for interchangeability in system design.

Current Sensors Replacement Considerations

Direct substitutes within the same series include the CR5220-5 for higher current capacity applications. Verify that any replacement maintains the 24V supply requirement and 4-20mA output format to ensure circuit compatibility without modification.
