Eaton EGR-5000-2A1GB0 Generator Relay - Modbus RTU RS-485
Part Number: EGR-5000-2A1GB0
Quick Summary
The Eaton generator relay EGR-5000-2A1GB0 provides advanced generator protection for critical industrial power systems. In many plants, coordinating protection across multiple generators creates wiring complexity and blind spots that delay fault isolation. The unit supports wide power supply ranges (19–300Vdc and 40–250Vac), RS-485 communications for Modbus RTU or DNP3 RTU, and a rich 16/9 I/O set with zone selective interlocking. Compliance details are provided by the manufacturer, so verify regional standards such as CE, UL, or IP ratings with Eaton. This combination delivers reliable protection while simplifying integration with existing SCADA, enabling faster outage recovery and improved asset uptime. Conformal coating on the boards and removable terminals further streamline installation in challenging environments.

FAQs
The EGR-5000-2A1GB0 combines 16 digital inputs, 9 outputs, two current sensing inputs, and a wide supply range (19-300Vdc, 40-250Vac) with generator-focused protection features such as metering, differential protection, and zone selective interlocking. Its RS-485 Modbus/DNP3 interfaces simplify integration with existing protection schemes and SCADA systems, reducing wiring complexity and improving fault isolation times.
RS-485 with Modbus RTU or DNP3 RTU provides a robust, industry-standard channel for real-time protection data and control signals. This enables easy interrogation of relay status, event logs, and metering data from a centralized SCADA system, improving visibility, diagnostics, and remote operation while reducing field wiring overhead.
Key specs include a dual power-supply range of 19-300Vdc and 40-250Vac, 50/60 Hz operation, 16 digital inputs and 9 outputs, plus 2 current sensing inputs. The relay supports current, voltage, power, and differential protection with 1A/5A sensing options, and features removable terminals for straightforward wiring and maintenance.
Compliances are listed as manufacturer-dependent. To ensure regional regulatory compliance (CE, UL, IP ratings, etc.), consult Eaton directly and request the applicable certificates for your market. They can confirm which standards apply to your installation and provide any required documentation for commissioning and audit readiness.
Installation benefits include conformal-coated circuit boards for harsh environments, semi-flush mounting, and removable terminals that speed field wiring and future upgrades. The unit’s extensive I/O and zone selective interlocking enable sophisticated protection schemes while minimizing disturbance to neighboring equipment, supporting rapid commissioning and reduced maintenance downtime.
