CR4260-30

Current Sensors Overview

The CR4260-30 is a loop-powered AC current transmitter manufactured by CR Magnetics Inc. It provides remote monitoring of AC sine wave currents with an input range of 0 to 30 A and produces a calibrated 4 mA DC to 20 mA DC output signal proportional to the average RMS input current. The device operates on a 24V supply within a frequency range of 50Hz to 400Hz. Key performance specifications include an accuracy of ±0.5% and a response time of 250ms. The operating temperature range is specified from 0°C to 60°C, ensuring reliable functionality in standard industrial environments.

Current Sensors Procurement Notes

Verify that the specific part number matches the required input current rating of 30A and the output signal specification of 4-20 mA DC. Confirm that the operating environment falls within the stated temperature range of 0°C to 60°C and frequency range of 50Hz to 400Hz. Ensure compatibility with the user-provided PLC power source for the output loop. Check for any specific mounting requirements regarding DIN rail or panel installation dimensions.

Current Sensors Selection Notes

Select this model when a loop-powered solution is required for monitoring AC currents up to 30A with high accuracy. The ±0.5% accuracy makes it suitable for precise industrial applications. Consider the 250ms response time for dynamic load monitoring. The rugged construction and simple wiring make it ideal for retrofitting existing control panels where space and power availability are constrained.

Current Sensors Part Context

This component belongs to the CR4220/CR4260 series of AC current transducers from CR Magnetics Inc. The series is designed for professional energy monitoring applications, providing sensors for current, voltage, frequency, power, and power factor.
