Eaton EMR-5000-2A0BA0 Motor Relay - Differential Protection
Part Number: EMR-5000-2A0BA0
Quick Summary
Eaton EMR-5000-2A0BA0 motor relay is engineered to protect motors and simplify protection schemes in industrial automation. Engineers often battle nuisance trips, miscoordination between protection layers, and opaque diagnostics in motor circuits. The device aligns with CE safety expectations and common IP-rated enclosures, but exact certifications vary by region and model and should be confirmed with Eaton. Built for reliability, it supports Modbus RTU or DNP3 RTU over RS-485 for remote monitoring and control, and offers differential protection, power protection and metering, and current/voltage metering. For cost- and time-sensitive projects, its 16 digital inputs, 9 digital outputs, removable terminals, and semi-flush mounting deliver installation flexibility and rapid field upgrades while maintaining robust protection.

Eaton Specification Sheet - EMR-5000-2A0BA0
RS-485 communications via Modbus RTU or DNP3 RTU enable remote monitoring and control, reducing field visits and speeding fault isolation. This supports integration with plant SCADA and maintenance systems for multi-motor drives in manufacturing lines and process plants. With 16 digital inputs and 9 digital outputs, the EMR-5000-2A0BA0 acts as a compact I/O hub, minimizing additional controllers and wiring while simplifying panel design and commissioning for packaging, food & beverage, and automotive manufacturing environments. Differential protection, power protection and metering, plus current and voltage metering, provide layered protection and energy analytics that reduce nuisance trips and improve coordination with upstream feeders in heavy industries. The device operates across a wide voltage window (19-300 Vdc, 40-250 Vac) at 50/60 Hz, supporting global equipment and diverse motor sizes, while removable terminals and EMR-4000 base-relay compatibility enable scalable upgrades. An IRIG-B URTD interface adds time synchronization for precise fault logging in power distribution and utility-scale applications.

FAQs
The EMR-5000-2A0BA0 supports Modbus RTU or DNP3 RTU over RS-485, enabling straightforward integration with existing plant networks and SCADA systems. With 16 digital inputs and 9 digital outputs, it can consolidate motor protection logic within a single enclosure, reducing wiring complexity and accelerating commissioning in multi-motor panels and process lines.
The relay offers differential protection, power protection and metering, and current and voltage protection and metering. This layered approach helps prevent nuisance trips, improves protection coordination with upstream feeders, and provides valuable energy data for efficiency initiatives and regulatory reporting in manufacturing and utilities sectors.
Yes. Its semi-flush mounting, removable terminals, and compatibility with the EMR-4000 base relay support scalable, retrofit-friendly installation in OEM control panels. The device also supports remote monitoring via RS-485 and provides rich metering data, aiding OEMs in delivering compact, compliant motor protection solutions for machine builders and system integrators.
Plan for semi-flush mounting in standard panels and ensure space for the 8.06 in × 8.7 in × 9.72 in enclosure footprint. Leverage removable terminals to simplify field wiring and ensure the 50/60 Hz operation with 19-300 Vdc / 40-250 Vac sensing is matched to local motor specs. Also consider IRIG-B URTD interface needs for time synchronization in advanced applications.
The EMR-5000-2A0BA0 is backed by Eaton’s warranty policy (1 year from installation or 18 months from shipment, whichever occurs first). ROI benefits come from reduced downtime through faster fault isolation, fewer nuisance trips, consolidated I/O, and remote diagnostics via RS-485, leading to lower maintenance costs and improved asset utilization over the motor fleet.
