DNM-844-50A

Overview

The DNM-844-50A is a four-channel current sense transformer manufactured by ICP DAS USA INC. It features a solid core design for non-invasive current measurement with a nominal rating of 50 A. The device operates within a frequency range of 0 Hz to 50 kHz and utilizes DIN rail mounting for industrial integration. It provides 3000 VDC isolation between modules, supporting signal attenuation from input ranges up to ±2000 A down to ±10 V output.

Feature Summary

• Four-channel configuration for simultaneous multi-phase monitoring
• Non-invasive solid core design eliminates circuit interruption
• Provides 3000 VDC electrical isolation between internal modules

Applications

• Industrial power distribution monitoring
• Multi-phase energy metering systems
• Motor control and protection circuits

Procurement Notes

Verify the specific model suffix against official ICP DAS documentation to confirm pinout compatibility and insulation ratings. Ensure the selected variant matches the required nominal current and frequency response for your application. Cross-reference datasheet specifications directly with manufacturer resources rather than distributor summaries to avoid discrepancies in technical parameters.

Selection Notes

Select this component when non-invasive monitoring of multiple AC or DC currents is required without breaking the conductor path. The 50 A rating suits moderate load applications, while the 50 kHz bandwidth supports harmonic analysis. Consider the DIN rail form factor for panel integration and verify that the ±10 V output range aligns with downstream data acquisition hardware inputs.

Part Context

This unit belongs to the DNM-844 series, which offers four-channel current transformation capabilities. The series supports high-current inputs attenuated to standard voltage levels, facilitating connection to PLCs or DAQ systems. The DNM-844-50A specifically denotes the 50 A nominal current variant within this family.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Verify compatibility with existing DIN rail profiles and terminal connections before considering alternative manufacturers.
