Eaton EGR-5000-2A0IA1 Generator Relay - RS-485 / Ethernet
Part Number: EGR-5000-2A0IA1
Quick Summary
Eaton generator relay is a protective device that monitors generator performance and triggers protective actions in industrial power systems. This addresses the common challenge of nuisance trips and incomplete protection coordination across control, metering, and remote monitoring layers. Certification specifics are not listed in the data sheet; please confirm CE, IP/SIL status with Eaton for exact approvals. The device supports remote communication over RS-485 and Ethernet, features extensive I/O (16 digital inputs, 9 outputs), and offers flexible protection logic with 5A/1A current sensing. In practice, this translates to improved reliability, faster fault isolation, and streamlined integration with existing protection schemes and SCADA systems, delivering tangible uptime and maintenance efficiency for generator installations.

FAQs
Start by mapping the 16 digital inputs and 9 outputs to your protection scheme, then connect the 19-300 Vdc / 40-250 Vac power supplies and confirm the projection mounting is supported in your panel. Use RS-485 for Modbus integration and the Ethernet RJ-45 for remote monitoring. Removable terminals simplify wiring changes and maintenance, while the Trip Coil Monitor option provides enhanced trip verification. Plan for compatibility with URTD or IRIG-B interfaces if required by your control system.
The EGR-5000-2A0IA1 supports Modbus over RS-485 and Ethernet RJ-45, enabling direct integration with common SCADA and PLC systems. This dual pathway supports remote monitoring, data logging, and coordinated protective actions across multiple devices. For time synchronization or high-accuracy protection schemes, IRIG-B compatibility is available as an I/O option, aiding grid-tied or large-scale generator configurations.
Yes. The unit is rated for 50/60 Hz operation and accepts a broad power supply range (19-300 Vdc, 40-250 Vac), making it adaptable to diverse regional power standards. This flexibility reduces the need for separate relays for different facilities and supports consistent protection behavior across sites.
This generator protection relay excels in large genset installations, backup power systems, and facilities requiring reliable protection coordination. Its 16 digital inputs and 9 outputs support complex interlocking and metering, while RS-485 Modbus and Ethernet enable centralized monitoring. Zone selective interlocking and Trip Coil Monitor options enhance selective tripping and fault localization in data centers, manufacturing lines, and critical process environments.
Eaton lists a one-year warranty from installation or eighteen months from shipment, whichever occurs first. For maintenance planning, verify coverage terms with Eaton and request any country-specific service options. Regular checks should include input/output wiring integrity, terminal tightness, communication link health (RS-485/Ethernet), and firmware or configuration backups to ensure long-term protection reliability.
