16 digital inputs, 9 digital outputs, and 2 current-sensing inputs give the EGR-5000-2A0GB1 rich I/O for protection coordination and status signaling. This density translates into simpler wiring schemes, reduced panel space, and more precise trip control, improving overall generator protection and metering. The URTD Interface, Trip Coil Monitor, and IRIG-B support enable accurate time synchronization and coordinated protection across multiple devices, essential for zone selective interlocking in large systems. Voltage sensing inputs, along with 1 voltage sensing input and a broad power-supply range of 19-300 Vdc and 40-250 Vac, allow reliable protection across global installations while maintaining compatibility with common industrial power architectures. Conformal coating on circuit boards enhances reliability in harsh environments, and removable terminals simplify field installation and maintenance. Modbus/DNP3 RTU over RS-485 provides straightforward SCADA integration, reducing commissioning time and supporting remote diagnostics. With a compact footprint (8.06 in L × 8.7 in H × 9.72 in W) and a weight of 9.259 lb, it fits standard panel budgets. The included 1-year warranty (or 18 months from shipment) lowers total cost of ownership, while the Eaton protection philosophy emphasizes long-term reliability and predictable performance across generator protection and metering tasks.

FAQs
When integrating the EGR-5000-2A0GB1, plan for its 8.06 in length, 8.7 in height, and 9.72 in width footprint, plus a weight around 9.259 lb to ensure panel fit. Utilize the removable terminals for efficient wiring and take advantage of projection mounting to simplify rack or cabinet installation. Ensure RS-485 communication lines are routed with proper isolation and terminate Modbus RTU or DNP3 RTU lines at the controller as per plant practice.
The device provides 16 digital inputs, 9 digital outputs, and 2 current-sensing inputs for comprehensive protection and metering. It supports voltage protection and metering, current protection and metering, and differential protection, with 50/60 Hz operation and wide power-supply ranges of 19-300 Vdc and 40-250 Vac. This enables precise trip coordination, accurate fault localization, and reliable protection across diverse generator configurations.
Yes. Designed for generator protection in standby and critical-load applications, the relay supports RS-485 communications (Modbus RTU/DNP3 RTU), zone selective interlocking, and IRIG-B timing options for synchronized protection. Its wide AC/DC voltage ranges and robust construction suit industrial facilities, data centers, and manufacturing environments seeking dependable generator protection and remote monitoring.
