Eaton EGR-5000-2B1CB1 Generator Relay - Modbus over Ethernet
Part Number: EGR-5000-2B1CB1
Quick Summary
Eaton generator relay is a robust protection device designed to safeguard generators by monitoring voltage, current, and phase conditions and triggering fast, coordinated trips. Engineers often struggle with wiring complexity and SCADA integration, so this relay minimizes field wiring with removable terminals and supports Modbus/DNP3 over Ethernet for seamless plant-wide visibility. When selecting a protection relay, verify critical certifications and enclosure requirements; look for SIL safety integrity considerations for safety-critical applications, CE marking for EU compliance, and appropriate IP protection for harsh environments. The result is improved reliability, easier maintenance, and lower lifecycle costs through tighter protection coordination and straightforward system integration.

Selling Policy 25-000 - Distribution and Control Products and Services
Eight digital inputs and nine digital outputs give the controller substantial signaling capacity, enabling faster fault indication and tighter protection coordination with fewer external interfaces. This directly reduces field wiring, simplifies panel layouts, and lowers installation costs while improving response accuracy in generator protection schemes. Application: generator switchgear and remote monitoring. Two analog inputs and two analog outputs enable precise metering and differential protection signals, supporting voltage and current monitoring across channels for accurate protection and metering. This ensures better fault discrimination and faster corrective actions in power generation systems. Modbus/DNP3 over Ethernet RJ-45 provides seamless SCADA integration and remote diagnostics, reducing on-site visits and enabling real-time visibility across multiple sites. URTD Interface, Sensitive Ground Input, and IRIG-B Trip Coil Monitor enhance protection accuracy and time synchronization for mission-critical applications. Conformal coating on circuit boards improves reliability in harsh environments, while removable terminals and projection mounting simplify installation and maintenance. The wide power supply range of 19-300 Vdc / 40-250 Vac supports diverse plant configurations, enabling faster commissioning and lower total ownership costs.

FAQs
The relay features removable terminals and projection mounting, designed to simplify field wiring and panel layouts. It supports a broad power range (19-300 Vdc / 40-250 Vac) and standard protection relays workflows, making it compatible with typical generator protection schemes and retrofits. Expect straightforward wiring, quick replacements, and ease of future upgrades.
It communicates over Ethernet using Modbus or DNP3 RTU, enabling direct SCADA integration and remote monitoring. This reduces on-site visits, improves fault visibility, and supports centralized control. The model also supports IRIG-B timing features for synchronized protection coordination in multi-site deployments.
Yes. With 2 analog inputs and 2 analog outputs, plus 8 digital inputs and 9 digital outputs, the EGR-5000-2B1CB1 supports differential protection, voltage protection, and metering. This enables precise fault discrimination, accurate energy monitoring, and improved protection coordination across generator feeds and connected loads.
The product provides a compliance note to contact the manufacturer for specific certifications. When procuring, confirm CE marking for EU compliance, SIL safety integrity considerations for safety-critical installations, and confirm enclosure IP ratings appropriate to your environment to ensure regulatory and operational alignment.
