Eaton EGR-5000-2B0BA0 Generator Relay - Modbus RTU RS485
Part Number: EGR-5000-2B0BA0
Quick Summary
Eaton generator relay is a robust protection device that guards generators in industrial plants and standby power systems. Operators contend with coordinating protection signals across distributed assets and avoiding unnecessary trips during transient faults. Key regional considerations include CE, SIL, and IP-related approvals, which influence installation scope and compliance planning. This model supports Modbus RTU over RS485, two analog inputs and two analog outputs, eight digital inputs, and nine outputs to streamline integration. With this, installation is straightforward in control panels and generator rooms, helping reduce downtime and maintenance costs. Its protection algorithms cover differential, power, current and voltage metering, delivering fast fault detection and enhanced reliability.

FAQs
The EGR-5000-2B0BA0 uses Modbus RTU over RS485, enabling direct communication with most PLCs and SCADA systems. Plan RS485 wiring with removable terminals for a clean panel layout, map digital and analog I/O to the control logic, and configure zone selective interlocking for selective trips. This minimizes wiring complexity and reduces commissioning time.
Key specs include power supply range 19-300 Vdc or 40-250 Vac, frequency rating 50/60 Hz, 8 digital inputs, 9 outputs, 2 analog inputs and 2 analog outputs, plus Modbus RTU over RS485 for remote monitoring and control. Ensure your generator and cabinet wiring align with these ranges and that communication networks support RS485 topology.
Yes. With differential, power, current, and voltage protection and metering, plus zone selective interlocking, the EGR-5000-2B0BA0 provides broad fault coverage and fast isolation. Its removable terminals and semi-flush mounting simplify installation in typical switchgear and generator rooms found in manufacturing and processing facilities.
Compliance details are region-specific; the data indicates manufacturer-based compliance. When evaluating, confirm regional approvals such as CE or SIL requirements with Eaton or your local distributor, and consider IP enclosure ratings for your environment. Verify documentation and test reports during procurement to ensure alignment with site safety and reliability standards.
ROI benefits come from reduced downtime due to faster fault detection, fewer mis-trips thanks to precise protection logic, and simplified wiring reducing installation costs. With removable terminals and durable design, maintenance intervals are predictable, and field upgrades can be performed quickly, minimizing labor costs during life-cycle maintenance.
