Eaton Generator Relay EGR-5000-2B1BB1 - Generator Protection Relay
Part Number: EGR-5000-2B1BB1
Quick Summary
Eaton generator relay EGR-5000-2B1BB1 protects generators and enables fast fault isolation in industrial power systems. Unprotected startups and miscoordination can trigger outages and costly downtime, especially in multi-generator plants. Certification considerations include CE compliance, SIL capability, and enclosure IP ratings, with exact approvals coordinated through Eaton for your region. This relay combines modular inputs and outputs, Modbus RTU or DNP3 RTU over RS-485, and wide power-supply ranges (19-300 VDC, 40-250 VAC), delivering robust reliability while simplifying integration with plant SCADA. By aligning protection, metering, and alarm signaling, it supports improved maintenance planning, faster commissioning, and reduced total cost of ownership.

FAQs
Begin by mapping the 8 digital inputs, 2 analog inputs, and 9 digital outputs to starter circuits, alarms, and interlocks. Use the removable terminals for quick wiring and verify RS-485 connections for Modbus RTU or DNP3 RTU. Follow Eaton's installation guide for protection settings and perform staged commissioning with your plant SCADA to confirm correct trip logic.
The relay includes built-in Modbus RTU and DNP3 RTU over RS-485, enabling secure, real-time data exchange with SCADA and protection schemes. It supports standardized alarms, setpoint transfer, and event logging, reducing miscommunications between protection relays and the control room. This minimizes downtime and improves operator responsiveness during generator faults.
Yes, the EGR-5000-2B1BB1 offers URTD Interface and IRIG-B time synchronization as I/O options, enabling precise event timing and compatibility with synchronized protection schemes. This is beneficial in plants with centralized timing, improved fault correlation, and easier post-event analysis. Verify compatibility with your existing URTD/IRIG-B sources during project scoping.
It senses voltages from 19-300 VDC and 40-250 VAC with 50/60 Hz operation, plus current protection and metering capabilities. It includes Sensitive Ground Input and Trip Coil Monitor for enhanced fault detection, and provides 8 DI/9 DO for control logic. These features support reliable generator protection and faster fault clearance in varied plant environments.
