Eaton EMR-4000-2A1IA1 Motor Relay - RS-485 & Ethernet

Feature → Business Impact → Application: Wide voltage range 19–300 VDC and 40–250 VAC enables single-stock simplicity across diverse motor loads and environments, reducing inventory while preserving protection integrity. This translates to lower BOM complexity and faster commissioning in process automation and packaging lines. Feature → 8 digital inputs and 5 digital outputs, plus 4 analog outputs, support complex logic and interlocking schemes without external add-ons, delivering tighter control of motor start/stop sequences and reduced external I/O wiring costs. Application: Industrial motor control panels and PLC-backed automation systems benefit from a compact, integrated I/O footprint. Feature → RS-485 Modbus/DNP3 RTU and Ethernet TCP communications provide flexible remote monitoring and control, enabling diagnostics, trend analysis, and predictive maintenance, cutting field service visits and improving uptime. Application: Data centers, beverage/food processing, and water/wastewater facilities rely on reliable remote data exchange and centralized supervision. Feature → Sensing inputs include Current Protection and Metering, Voltage Protection and Metering, and Power Protection and Metering, delivering comprehensive electrical protection and energy analytics that support compliance and cost optimization. Application: Energy management and safety-critical motor applications where metering accuracy informs budget and efficiency initiatives. Feature → Zone selective interlocking (ZSI) and IRIG-B Sensitive Ground Input URTD Interface enhance protection coordination and time synchronization, reducing miscoordination events and improving fault isolation. Application: Critical manufacturing lines and high-availability motors where fast fault isolation minimizes production losses. Feature → Motor relay delivery keeps the focus on motor health rather than peripheral hardware, simplifying installation and future upgrades within Eaton’s E-Series ecosystem. Application: OEMs and end-users upgrading legacy systems or expanding motor fleets. Feature → 1-year warranty under Eaton policy provides assurance against early-life failures, supporting TCO objectives and maintenance planning. Application: Plant engineers planning lifecycle maintenance and supplier reliability.
