Eaton EGR-5000-2B0BA1 Generator Relay - RS-485 Modbus RTU
Part Number: EGR-5000-2B0BA1
Quick Summary
Eaton generator relay is designed to protect and monitor generator sets in critical power systems. In practice, engineers often confront nuisance trips and slow fault isolation that prolong downtime. This device supports Modbus RTU or DNP3 RTU over RS-485, with RS-485 communication enabling remote integration to SCADA. Compliance details are supplied by the manufacturer, and typical configurations may include CE, UL, and SIL capabilities—verify with the datasheet. The Eaton generator protection relay helps ensure reliable operation, with robust voltage sensing and current protection, while scalable I/O supports future expansion. By aligning protection settings to generator protection relay capabilities, businesses gain improved reliability, faster fault diagnosis, and lower maintenance costs.
