Eaton EMR-4000-2A0LB1 Motor Relay - Fiber Optic Ethernet

Eight digital inputs and five digital outputs provide flexible control and monitoring, reducing panel wiring and enabling safe interlocking in motor control scenarios. This translates to faster commissioning and lower long-term maintenance costs in automated facilities. Four analog outputs offer real-time process signals for drive safety or performance tweaks, improving feedback loops and process stability in heavy-duty applications. Phase current handling of 5A and 1A supports precise motor protection while keeping wiring complexity manageable, resulting in safer starts and reduced fault-induced wear. Sensing inputs deliver current, voltage, and power protection and metering, enabling accurate energy accounting and protection coordination across multiple feeders. Conformal coated circuit boards and rugged fiber-optic communications minimize EMI susceptibility and environmental risk, boosting reliability in harsh industrial environments. The IRIG-B URTD interface and Modbus/DNP3 TCP over LC duplex fiber provide seamless integration with existing control systems, enabling scalable architectures and straightforward migration from legacy relays. With a compact footprint and a 19-300Vdc / 40-250Vac operating range, installation in crowded control panels is simplified, while the Eaton warranty adds reassurance for uptime commitments and total cost of ownership.
