Eaton motor relay EMR-5000-2B0EB0 - Differential Protection
Part Number: EMR-5000-2B0EB0
Quick Summary
Eaton motor relay EMR-5000-2B0EB0 is a motor protection relay designed for reliable protection and monitoring of industrial motors in automated plants. Engineers often struggle to coordinate protection logic, diagnostics, and fieldbus integration across D-SUB and RS-485 networks, leading to delays in fault isolation and extended downtime. Key standards approvals for this class depend on configuration, so confirm CE, SIL, or IP ratings with Eaton for your exact install. By integrating differential protection, metering, and Profibus-DP connectivity, this device delivers robust motor protection while enabling commissioning efficiency and easier maintenance. This translates into reduced outages and improved asset utilization for energy-intensive operations.

FAQs
EMR-5000-2B0EB0 extends the EMR-4000 base relay with additional I/O (2 analog inputs, 2 analog outputs, 8 digital inputs, 9 digital outputs) and Profibus-DP over RS-485 connectivity. It preserves removable terminals for easy wiring and supports the URTD IRIG-B option. This provides a straightforward upgrade path while maintaining existing protection logic and bus infrastructure.
Removable terminals simplify installation, testing, and field maintenance by reducing live-wiring time. Plan for semi-flush mounting and ensure correct torque on terminal screws. Verify compatible power supply ranges (19-300 Vdc, 40-250 Vac) and appropriate fieldbus connections (Profibus-DP over RS-485) to minimize commissioning delays and wiring errors.
The relay offers differential protection, voltage and current protection with metering, and power metering with zone selective interlocking. With 2 analog inputs/outputs and 8/9 digital I/O, it provides robust fault detection, accurate monitoring, and rapid fault localization. These features support reliable motor protection in demanding automation environments.
This device is well-suited for industrial motor protection in automated production lines, conveyors, pumps, and machine tools. Its Profibus-DP communication enables seamless integration with PLCs, while the array of I/O and metering capabilities supports advanced protection schemes, commissioning efficiency, and proactive maintenance in energy-intensive facilities.
Eaton provides a one-year warranty from installation or an 18-month term from shipment, per policy 25-000. For certifications and compliance specifics, confirm with Eaton for your configuration.
