Eaton EMR-4000-2A0HA0 Motor Relay - IEC 61850/URTD
Part Number: EMR-4000-2A0HA0
Quick Summary
Eaton motor relay EMR-4000-2A0HA0 provides motor protection and control for industrial drive systems. Engineers often struggle to coordinate protection, metering, and remote communications within compact control panels. This device supports IEC 61850 and Modbus TCP over Ethernet RJ-45, plus URTD timing with IRIG-B, enabling interoperable protection schemes. The unit combines 5A/1A phase protection, 8 digital inputs, 4 analog outputs, and 5 digital outputs to deliver robust protection and monitoring, reducing downtime and enabling remote diagnostics. In industrial automation, this translates to safer starts, energy metering, and improved system uptime while delivering scalable, networked motor protection for modern manufacturing environments.
