Eaton EMR-5000-2B0IB0 Motor Relay - RS-485 & Ethernet
Part Number: EMR-5000-2B0IB0
Quick Summary
Eaton motor relay EMR-5000-2B0IB0 provides advanced motor protection for industrial drives and switchgear. Engineers often confront downtime from faults, nuisance trips, and complex protection schemes that slow commissioning. Compliance details are provided by the manufacturer; regional certifications such as CE, SIL, or IP ratings should be verified with Eaton. Across plant-wide control, this relay supports remote monitoring and integration via RS-485 and Ethernet, delivering reliable protection with scalable I/O and field-installable terminals. By consolidating protection, metering, and communication in a single device, it reduces wiring complexity and lifecycle costs for motor control projects.

FAQs
The EMR-5000-2B0IB0 uses semi-flush mounting and features removable terminals, which simplifies field wiring and reduces commissioning time. It also supports flexible I/O wiring through its 2 analog inputs, 2 analog outputs, 8 digital inputs, and 9 digital outputs, enabling adaptable installation in diverse motor control panels.
This relay offers differential protection, voltage protection and metering, current protection and metering, and power metering. By centralizing sensing and protection, it improves fault discrimination, reduces nuisance trips, and enables precise protection coordination across motor drive configurations.
The EMR-5000-2B0IB0 supports Modbus/ DNP3 RTU over RS-485 and Modbus/ DNP3 TCP over Ethernet RJ-45, enabling robust, industry-standard interfaces for SCADA, DCS, and PLC systems with secure remote monitoring and control.
Key considerations include mounting method (semi-flush) for space efficiency, conformal coating on circuit boards for harsh environments, and the IRIG-B URTD interface option for time synchronization. This combination enhances reliability, reduces maintenance, and supports accurate protection coordination.
Eaton provides a standard warranty policy (1 year from installation or 18 months from shipment, whichever comes first). For coverage specifics, installation guidance, and service options, contact Eaton or your authorized distributor to discuss extended warranties and support arrangements.
