Eaton EMR-4000-2A1KA1 Motor Relay - IEC 61850 Fiber
Part Number: EMR-4000-2A1KB0
Quick Summary
The Eaton EMR-4000-2A1KA1 motor relay provides integrated protection, control, and metering for industrial motors in automation panels. Engineers frequently struggle with multi-protocol integration, data visibility, and reliable remote diagnostics in harsh environments. With IEC 61850 over fiber optic Ethernet and Modbus/DNP3 TCP, the EMR-4000-2A1KA1 supports resilient, standards-based communication. Certification status varies by region, so confirm CE, SIL, or IP ratings with the manufacturer to ensure regulatory compliance. This combination drives reduced downtime, accurate energy metering, and scalable motor protection for energy-intensive operations. Designed for modular integration in control cabinets, it offers 8 digital inputs, 5 digital outputs, and 4 analog outputs, enabling straightforward wiring and commissioning. Implementation in retrofit projects reduces risk by consolidating protection, metering, and communication into a single device for industry.
