Eaton EMR-5000-2B1LA0 Motor Relay - Mbus/DNP3 TCP
Part Number: EMR-5000-2B1LA0
Quick Summary
Eaton motor relay EMR-5000-2B1LA0 provides integrated protection and control for industrial motors in automation systems. Engineers often grapple with fragmented protection logic, disparate diagnostics, and complex wiring when scaling motor networks; this device consolidates protection, communication, and monitoring in a single module. Compliances vary by region, but Eaton supports industry-standard docs and regional certification processes, with potential CE/UL considerations and IP-related guidance available through the manufacturer. This combination helps reduce downtime, streamline maintenance, and accelerate commissioning, while enabling remote visibility via Mbus TCP or DNP3 TCP/UDP over LC duplex fiber Ethernet. In short, it balances robust motor protection with future-ready connectivity for modern plant floors.

FAQs
Begin by mapping the EMR-5000-2B1LA0 IO to your motor circuit, then mount the unit using the semi-flush mounting method. Removeable terminals simplify wiring changes, and the 8/9 digital IO along with 2 analog channels support step-by-step integration. Plan a staged commissioning with a parity check of Mbus TCP or DNP3 connections to ensure seamless communication with your SCADA system.
The device supports a broad range: 19–300 V DC and 40–250 V AC at 50/60 Hz. This wide spectrum enables compatibility with both DC bus motors and traditional AC motors, reducing the need for multiple protection relays and simplifying inventory management across mixed motor fleets.
EMR-5000-2B1LA0 provides Mbus TCP and DNP3 TCP/UDP over LC duplex fiber optic Ethernet, enabling secure, scalable remote monitoring and integration with modern SCADA systems. This makes it suitable for distributed installations where fiber-backed Ethernet is preferred for reliability and bandwidth.
Compliances are managed with the manufacturer, and regional certification processes may require confirmation of CE, UL, or IP-related approvals. Always reference the Eaton specification sheet and contact support to align on local regulatory requirements and any needed documentation for your installation site.
You’ll gain through consolidated protection and IO, reduced wiring, and centralized diagnostics, which lowers mounting time, speeds fault isolation, and decreases spare part inventory. Remote monitoring reduces maintenance trips, while integrated metering supports energy management initiatives, delivering a faster payback in automation-heavy environments.
