Eaton Specification Sheet - EMR-5000-2B1IA1
Flexible I/O and communications enable precise protection and diagnostics in a compact footprint. Feature → Business Impact → Application: 2 analog inputs, 2 analog outputs, 8 digital inputs, and 9 digital outputs centralize sensing and control, reducing wiring complexity and enabling faster fault diagnosis in automated lines. This translates to measurable uptime gains and simplified panel wiring for machine builders and integrators in manufacturing environments. The relay includes RS-485 Modbus and Ethernet TCP/IP connectivity, allowing remote monitoring and setpoint management from a single device, which lowers service calls and accelerates commissioning in process industries. Application: motor protection relays in packaging and automotive assembly lines seeking quick fault isolation and remote accessibility. The protection suite covers voltage, current, power, and differential protection, delivering improved safety margins and compliance with electrical standards. Application: critical motors in oil and gas or power distribution projects requiring robust protection logic. Zone selective interlocking is supported (1), enabling coordinated fault isolation to minimize system impact. Application: medium-voltage motor banks and distribution panels seeking selective tripping during faults. Projection mounting and removable terminals simplify installation and future maintenance. Application: retrofit projects and OEM builds needing flexible assembly and easy field servicing. The EMR-4000 base compatibility ensures scalable protection upgrades without replacing the entire protection scheme. Application: expanding existing protection architectures with a single, common relay family. Sensing inputs cover voltage protection and metering, current protection and metering, power protection and metering, and differential protection, delivering a single source of truth for motor health analytics. Application: condition-based maintenance programs and energy management initiatives. The 50/60 Hz frequency rating and 19-300 VDC/40-250 VAC input ranges support broad regional motor control standards, reducing regional variants.
