Eaton EGR-5000-2A1BA1 Generator Relay - Modbus RTU
Part Number: EGR-5000-2A1BA1
Quick Summary
Eaton generator relay is a core protection device for generator systems in standby or prime power applications. Engineers often struggle with configuring protection logic and remote communication in harsh environments, risking unwanted trips and extended downtime. Certification requirements vary by region; for this model, compliances are specified by the manufacturer, with CE compliance for European use, SIL-rated protection logic for critical services, and rugged enclosure considerations commonly evaluated. The unit supports Modbus RTU or DNP3 RTU over RS-485 and offers 16 digital inputs and 9 outputs, enabling comprehensive protection schemes, metering, and coordination with other protective devices to improve reliability and reduce maintenance costs.

Selling Policy 25-000 - Distribution and Control Products and Services
RS-485 communications with Modbus RTU and DNP3 RTU provide scalable remote monitoring and protection coordination, reducing field visits. The unit includes 16 digital inputs, 9 outputs, and two phase current sensing inputs, enabling comprehensive protection logic, metering signals, and control actions across generator and switchgear ecosystems. In practice, this means faster trip schemes, better fault isolation, and tighter integration with supervisory control systems used in manufacturing and data centers. Power supply range of 19-300 Vdc and 40-250 Vac supports both DC and AC powered protection, while 50/60 Hz operation ensures compatibility with global grids, reducing inventory and simplifying procurement. I/O options URTD Interface, IRIG-B, Trip Coil Monitor, and Sensitive Ground Input offer time synchronization, monitoring, and sensitive ground detection for critical infrastructure reliability. Projection mounting and removable terminals streamline installation and maintenance, with compact dimensions and Weight suitable for space-constrained control cabinets. Zone Selective Interlocking (ZSI) enhances selective protection, minimizing disruption during faults and protecting adjacent equipment. Warranty and service options from Eaton contribute to lower lifecycle costs and predictable support across regions.

FAQs
The EGR-5000-2A1BA1 supports 16 digital inputs and 9 outputs, phase current sensing inputs, and a broad power range (19-300 Vdc, 40-250 Vac) with 50/60 Hz. It uses projection mounting with removable terminals, making it compatible with standard control cabinets and Eaton’s URTD/IRIG-B options for synchronization. Confirm physical fit, terminal labeling, and communication wiring (RS-485 for Modbus RTU/DNP3 RTU) during installation to ensure seamless integration with your generator and SCADA system.
The relay provides comprehensive protection functions for generator systems, including Power Protection, Metering, Differential Protection, and Voltage and Current Protection. Communication is via RS-485 supporting Modbus RTU and DNP3 RTU, enabling remote monitoring and integration with SCADA. The unit also offers Zone Selective Interlocking (ZSI) to minimize outage impact and 1 input voltage sensing to coordinate protection with the plant’s electrical network.
Yes. Its 16 digital inputs, 9 outputs, and flexible I/O options (URTD Interface, IRIG-B, Trip Coil Monitor, Sensitive Ground Input) support precise coordination and time synchronization essential for data centers and critical infrastructure. RS-485 communications enable remote monitoring and control, helping ensure uptime and rapid fault isolation in these environments.
Compliances on this model are specified by the manufacturer. Typical assessments for generator protection relays include CE marking for European compliance, SIL-rated logic for critical protection schemes, and enclosure protection considerations. Verify exact certifications with Eaton to meet regional regulatory requirements and project specifications.
The device follows Eaton’s Selling Policy 25-000 warranty: one year from installation or eighteen months from shipment, whichever occurs first. Eaton also offers service and spare parts support, which helps reduce maintenance downtime and protects long-term return on investment for protection relays in mission-critical applications.
