FAQs
The EMR-5000-2B1HA1 is an Eaton motor protection relay combining protection, metering, and Ethernet-based communication. It features 2 analog inputs, 2 analog outputs, 8 digital inputs, 9 digital outputs, and supports zone selective interlocking. It enables fast fault detection, comprehensive motor diagnostics, and straightforward integration with existing protection architectures.
It supports IEC 61850 over Ethernet RJ-45, along with Modbus TCP and DNP3 TCP/UDP. This combination provides interoperability with modern protection systems, SCADA, and DCS networks, reducing integration risk and enabling seamless data exchange for protection coordination, monitoring, and energy management across plant networks.
The device uses removable terminals and a projection mounting method for flexible cabinet placement. With a compact footprint and 50/60 Hz operation, it simplifies panel upgrades and new builds, reduces wiring errors, and speeds commissioning by consolidating sensing, control, and communication into a single protective relay.
Applications with multiple motors and critical loads, such as conveyors, pumps, and fans in manufacturing and process industries, benefit from zone selective interlocking. It improves protection coordination, minimizes arc-flash risk, and shortens outages by isolating faults to the affected zone while maintaining service to other motors.
Eaton provides a one-year warranty from installation or eighteen months from shipment, whichever comes first, along with access to technical support and product documentation. This supports ongoing maintenance planning, firmware updates, and replacement parts to maintain protective reliability.
