Eaton EGR-5000-2B1IA1 Generator Relay - 50/60 Hz
Part Number: EGR-5000-2B1IA1
Quick Summary
Eaton generator relay protects generator sets by monitoring faults and enabling fast, reliable trips. This smart protection device is designed to keep critical power supplies online while minimizing unwanted outages. Engineers often contend with mis-trips, slow fault recognition, and integration challenges when protection logic cannot seamlessly share data with plant controls. The EGR-5000-2B1IA1 uses flexible I/O, RS-485 Modbus communication, and a wide supply voltage range to fit diverse genset installations. Compliance details are provided by the manufacturer, and regional certifications should be verified on your project documentation. With its projection mounting, removable terminals, and comprehensive metering inputs, this relay delivers scalable protection for standby and prime power applications while reducing wiring complexity and maintenance costs.

Selling Policy 25-000 - Distribution and Control Products and Services
The EGR-5000-2B1IA1 provides eight digital inputs, nine digital outputs, and two analog inputs with two analog outputs, enabling complex protection schemes and local signaling without external hardware. This dense I/O set supports simultaneous protection against voltage, current, and differential faults, reducing wiring complexity and speeding commissioning for large generator sets and prime power installations. This translates to tangible uptime gains and easier panel layouts. The relay also supports Modbus RTU over RS-485 and URTD interface options with sensitive ground input and trip coil monitor, plus optional IRIG-B timing. Seamless SCADA integration lowers diagnostic time and enhances remote monitoring, which drives lower maintenance costs over the asset lifecycle.
