Eaton Specification Sheet - EMR-5000-2B1KB0
I/O flexibility with eight digital inputs, nine digital outputs, two analog inputs, and two analog outputs, plus removable terminals. This configuration reduces wiring complexity and installation time, improving commissioning efficiency for motor protection relay projects. In practical terms, technicians can tailor I/O to the motor control sequence, enabling precise monitoring and interlocks in compact control panels. Communication and interoperability are enhanced by IEC 61850 over LC duplex fiber optic Ethernet and Modbus/DNP3 TCP over fiber, delivering unified data exchange and easier integration with modern automation networks for substations and manufacturing floors. Protection features include voltage, current, differential protection and metering, enabling early fault detection and reducing unplanned downtime in drive systems and power management. Base compatibility with EMR-4000 and the URTD Interface options provides a clear upgrade path and simplified retrofit in existing installations. A rugged design with conformal coating and a wide operating range (19–300 Vdc / 40–250 Vac, 50/60 Hz) supports dense panel layouts and challenging environments, while 5A/1A phase current ratings ensure reliable protection for motor loads.
