Eaton EMR-5000-2A0CA1 Motor Relay - Modbus TCP
Part Number: EMR-5000-2A0CA1
Quick Summary
Eaton EMR-5000-2A0CA1 motor relay is designed to protect, monitor, and control motors in industrial networks. When motor protection and remote monitoring aren’t aligned, you risk nuisance trips, unplanned downtime, and costly maintenance. Compliances are managed by the manufacturer; verify CE, SIL, or IP ratings with Eaton for your installation. With Modbus TCP or DNP3 TCP/UDP over Ethernet RJ45, 16 digital inputs, 9 digital outputs, and an IRIG-B interface, the EMR-5000-2A0CA1 provides open Ethernet integration for scalable protection schemes. This supports OEMs and end users seeking reliable, extensible motor protection with centralized diagnostics, faster fault isolation, and easier commissioning across the plant. Its compatibility with the EMR-4000 base relay streamlines upgrades without redistributing control wiring.

FAQs
The EMR-5000-2A0CA1 is designed as a base-compatible motor protection relay that can replace or retrofit within EMR-4000-based installations. It uses removable terminals for quick wiring changes and preserves the same physical footprint, allowing plug-and-play upgrades. For retrofit projects, verify wiring schematics, confirm IO mapping, and align Modbus TCP or DNP3 configurations with your existing SCADA, reducing commissioning time and minimizing cabinet downtime.
Key protections include Power, Voltage, and Current Protection and Metering, plus Differential Protection and Zone Selective Interlocking. These features provide precise fault detection, energy metering, and fast isolation to minimize unplanned downtime. The 16 DI / 9 DO IO set supports robust interlocks and safe-start sequences, while the IRIG-B interface enables time-stamped events for accurate fault analysis and maintenance planning.
Yes. The EMR-5000-2A0CA1 supports Modbus TCP and DNP3 TCP/UDP over Ethernet RJ45, enabling seamless integration with standard industrial networks, SCADA, and energy management systems. This enables centralized diagnostics, remote fault reporting, and scalable motor protection across plant-wide installations, while maintaining compatibility with Ethernet-based time synchronization and external control logic.
Compliance status is listed as 'Contact Manufacturer' in the data. To satisfy regulatory and safety requirements, contact Eaton directly to confirm CE, SIL, IP, or any industry-specific certifications for your target markets and installation conditions. This ensures alignment with your plant safety programs, risk assessments, and customers’ certification needs before field deployment.
The EMR-5000-2A0CA1 delivers faster fault isolation, reduced downtime, and simplified maintenance through open Ethernet communications, extensive IO, and upgrade path from EMR-4000.
