Eaton
Part number
EMR-5000-2B1FB0

Quick Summary

The Eaton motor relay EMR-5000-2B1FB0 protects and controls motors in industrial automation applications. Integrating remote monitoring, fiber communication, and protection logic without multiple devices remains a common challenge. Compliance details vary by region; consult Eaton's datasheet for CE, SIL, and IP-related certifications. This compact, modular relay reduces wiring complexity by offering Modbus RTU or DNP3 RTU over fiber and scalable protection features. In practice, it enables remote diagnostics, improves uptime, and lowers maintenance costs across motor-driven processes. With inputs, outputs, and URTD IRIG-B/sensitive-ground options, it suits diverse industrial drives while maintaining installation efficiency.

FAQs

Yes, the EMR-5000-2B1FB0 is designed as a compatible upgrade path from the EMR-4000 base relay. It uses removable terminals and a semi-flush mounting method, which simplifies field wiring and reduces installation time. This makes retrofits straightforward in existing motor protection architectures while preserving familiar protection logic and IO configurations.
The unit provides 2 analog inputs, 2 analog outputs, 8 digital inputs, and 9 digital outputs, enabling rich protection and metering schemes. It supports Modbus RTU or DNP3 RTU over Fiber Optic ST, delivering EMI immunity and robust remote diagnostics in harsh environments, with a 50/60 Hz frequency rating suitable for global installations.
This relay excels in motor protection for large drives, pumping stations, and process lines where remote monitoring, precise protection, and fiber-based communication are required. Its sensing inputs cover differential, voltage, current, and metering protections, making it suitable for power quality monitoring, fault isolation, and coordinated protection in manufacturing and utilities.
Compliance specifics are provided by the manufacturer and can vary by region. The Eaton datasheet and product page should be consulted for CE, SIL, IP-related certifications and any region-specific approvals. For formal validation, refer to the Eaton specification sheet and installation guides linked in the product downloads.
The product carries Eaton’s warranty policy of one year from installation or eighteen months from shipment, whichever occurs first. ROI benefits come from reduced wiring, fewer components, improved uptime through remote fault reporting, and simplified upgrades from EMR-4000, resulting in lower maintenance and faster fault resolution.
