Eaton EMR-5000-2A1IA0 Motor Relay - RS-485 & Ethernet

The RS-485 Modbus RTU and Ethernet TCP/IP communications enable seamless integration into existing control networks, reducing commissioning time and enabling remote diagnostics—a clear productivity gain for control engineers in manufacturing and process industries. This capability translates to lower on-site maintenance costs and faster fault isolation during peak production periods, supporting predictable MTBF improvements. The EMR-5000-2A1IA0 also provides extensive sensing and protection functions, including differential protection, voltage protection and metering, and current protection and metering. The business impact is improved equipment protection, better energy accountability, and reduced risk of undetected faults in high-value motors, which is critical for uptime in conveyors, pumps, and fans. Its 16 digital inputs and 9 digital outputs offer flexible control logic and automation sequencing, reducing hardware footprint and wiring complexity in panel builds, while URTD interface IRIG-B and Sensitive Ground Input enable precision timing and robust grounding for noisy industrial environments. Compatibility with EMR-4000 base relays and a semi-flush mounting option simplifies retrofits and new installations alike, cutting installation time and ensuring a neat, service-friendly panel. Zone selective interlocking (1) enhances selective fault isolation, improving safety and reducing collateral damage during faults. In practice, technicians appreciate removable terminals for quick field maintenance, and the 19-300 Vdc / 40-250 Vac power range supports multi-volt-site deployments, helping you standardize components across facilities and reduce spares inventory.
