1191986

Overview

The Phoenix Contact 1191986 is a current transducer designed for measuring AC, DC, and distorted currents within a range of 0 A to 125 A. It features a Modbus/RTU interface via RS-485 for digital data processing. The device operates on a power supply voltage between 9.6 VDC and 30 VDC. It utilizes push-in terminal connections and is mounted on a DIN rail. The housing is made of polyamide (PA) with an IP20 rating. Operating temperatures range from -40 C to +60 C.

Feature Summary

• Configurable via USB-C web server without requiring 24 V DC power
• Supports measurement of AC, DC, and distorted currents
• Provides Modbus/RTU interface for digital data handling

Applications

• Industrial automation systems requiring current monitoring
• Energy management applications involving AC or DC load analysis
• Process control environments utilizing Modbus communication protocols

Procurement Notes

Verify the specific input/output configuration matches the application requirements, as the ECM-UC series includes variants for different current ranges. Confirm that the Modbus/RTU interface aligns with the existing network infrastructure. Ensure the operating temperature range suits the installation environment. Check for any recent product change notices regarding firmware or hardware revisions.

Selection Notes

Select this model when digital output via Modbus/RTU is required instead of analog signals. Consider the USB-C configuration capability if field setup without external power is necessary. Evaluate the 0 A to 125 A measurement range against peak load expectations. Compare with other ECM-UC variants if different input types or communication protocols are needed.

Part Context

This component belongs to the Phoenix Contact ECM-UC series of signal conditioners and converters. These devices are engineered for precise current measurement in industrial settings. The series emphasizes flexible configuration options and robust connectivity standards to facilitate integration into modern automated systems.

Replacement Considerations

Check for updated part numbers within the same ECM-UC family that may offer enhanced features or revised specifications. Verify compatibility with existing mounting rails and wiring configurations before substituting.
