Eaton Specification Sheet - EMR-5000-2B1EB1
The EMR-5000-2B1EB1 combines a broad power range with advanced protection functions, reducing nuisance trips and extending motor life in demanding industrial environments. The 19–300 Vdc and 40–250 Vac inputs cover diverse supply conditions, while 50/60 Hz operation ensures compatibility with global motor standards. This translates into fewer panel changes during plant upgrades and quicker fault isolation, improving overall line availability. The inclusion of current, voltage, power protection and differential protection delivers comprehensive fault coverage, enabling faster diagnosis and reduced maintenance costs in pumps, fans, and conveyors. In practice, engineers gain clearer protection curves and a safer startup sequence, lowering risk and accelerating commissioning in new builds or retrofits. The platform’s scalable protection supports future expansion without a full system redesign.

FAQs
When installing the EMR-5000-2B1EB1, plan for projection mounting and removable terminals to simplify service tasks. Ensure a stable 19–300 Vdc or 40–250 Vac supply, with 50/60 Hz operation, and synchronize with the EMR-4000 base relay if extended protection is required. Route Profibus-DP RS-485 wiring carefully and observe URTD/IRIG‑B interface options to maximize reliability in harsh plant environments.
Key specs include operation from 19–300 Vdc and 40–250 Vac at 50/60 Hz, with current ratings of 5A and 1A, and IO: 2 analog inputs, 2 analog outputs, 8 digital inputs, and 9 digital outputs. It supports Profibus-DP over D-Sub/RS-485 and offers zone selective interlocking. This combination supports precise protection, metering, and control in motor-driven applications.
Yes. The EMR-5000-2B1EB1 includes Profibus-DP communication over D-Sub/RS-485, enabling seamless integration with PLCs and SCADA systems. This facilitates remote diagnostics, centralized protection curves, and faster fault isolation across motor drives in complex manufacturing lines.
Maintenance benefits include removable terminals for easier field servicing and projection mounting that simplifies replacements. The system is designed to work with the EMR-4000 base relay for modular upgrades, and it supports IRIG-B and URTD I/O options for extended monitoring. Adhere to Eaton’s installation guidelines and schedule periodic checks of protection settings to sustain reliability.
The product carries Eaton’s standard warranty of one year from the date of installation or eighteen months from shipment, whichever occurs first. For service continuity, rely on Eaton’s authorized support network to confirm certification status, obtain updated protection curves, and access replacement parts or firmware updates as needed.
