FAQs
For retrofits, plan semi-flush mounting and utilize removable terminals to simplify wiring in existing control panels. Verify power supply compatibility with 19-300 Vdc or 40-250 Vac and confirm RS-485 Modbus addressing for PLC integration. The 8/9 IO count supports upgrading protection schemes without reworking other devices.
The EGR-5000-2B1IA0 supports Modbus RTU over RS-485, enabling remote monitoring and control via standard PLC or SCADA systems. This facilitates centralized event logging, trip coordination, and integration with broader protection schemes across multiple generators.
Yes. With 8 digital inputs, 9 digital outputs, 2 analog IO, and advanced protection functions (differential, current, voltage protection and metering), the relay supports reliable protection coordination, fast fault detection, and time-synchronized signaling essential for mission-critical environments like data centers.
Compliances are provided by the manufacturer. The product is designed as a generator protection relay and supports typical industry practices for generator protection; specific certifications (such as CE or SIL) should be confirmed with Eaton for your installation and regulatory requirements.
Expected benefits include reduced downtime through rapid fault detection, improved protection coordination, and easier maintenance due to removable terminals and modular IO. The model comes with a one-year warranty (or 18 months from shipment, whichever occurs first), supporting long-term reliability and predictable maintenance budgeting.
