Eaton EMR-3000-2A1KA0 Motor Relay - IEC 61850 over LC Duplex Fiber Optic Ethernet
Part Number: EMR-3000-2A1KA0
Quick Summary
Eaton EMR-3000-2A1KA0 motor relay is a rugged protection and signaling device for industrial motors used in automation and drive systems. Engineers face the challenge of integrating motor protection, time synchronization, and real-time communications across demanding plant environments. This model delivers IEC 61850 communications over LC duplex fiber optic Ethernet, IRIG-B time interfaces, and URTD options for precise timing and remote diagnostics. By consolidating control, protection, and communications in a single unit, it simplifies wiring and reduces panel footprint. The device also supports current protection and metering, alongside standard mounting and multilayer I/O, enabling faster commissioning and improved uptime. In manufacturing and process automation, this translates to lower total cost of ownership and greater system reliability.
