Eaton EGR-5000-2A0BB0 Generator protection relay - Modbus RTU / DNP3 RTU over RS-485
Part Number: EGR-5000-2A0BB0
Quick Summary
The Eaton generator protection relay EGR-5000-2A0BB0 provides robust protection and monitoring for generator systems. Engineers often struggle to synchronize protection logic with remote monitoring while keeping installation time and total cost under control. Compliance for these devices is region-specific and should be confirmed with the manufacturer; typical deployments look for regulatory marks where applicable and regionally required. With Modbus RTU or DNP3 RTU over RS-485, 16 digital inputs, 9 outputs, and conformal-coated circuit boards, this relay supports reliable protection while reducing panel footprint and maintenance. This combination simplifies commissioning, improves uptime, and supports scalable protection schemes for industrial, data-center, and energy-generation applications.

Selling Policy 25-000 - Distribution and Control Products and Services
Expanded I/O capability: 16 digital inputs and 9 outputs enable comprehensive protection logic within a single device, reducing external interlocks and wiring complexity. This translates to shorter installation times and lower wiring error rates in industrial generator protections and multi-point signaling. In practice, engineers can implement sophisticated protection and signaling schemes without added hardware or panel space. Robust communications: RS-485 with Modbus RTU or DNP3 RTU delivers reliable data exchange to SCADA and maintenance systems, accelerating fault diagnosis and remote control. Operators gain visibility across generator fleets, enabling faster response times and reduced downtime in critical facilities such as data centers and utilities. Wide power compatibility: A dual power supply range of 19–300 Vdc and 40–250 Vac accommodates diverse generator sets and control power environments, simplifying procurement and field wiring. This flexibility supports mixed power architectures and eases retrofit projects without sacrificing protection fidelity. Comprehensive sensing and protection: The device supports current protection and metering, differential protection, power protection and metering, and voltage protection and metering, spanning multiple protection zones. This breadth reduces the need for auxiliary relays and yields tighter coordination during faults, improving system reliability for industrial plants and distributed generation. Durable construction and serviceability: Conformal coated circuit boards protect against moisture and contaminants, while removable terminals enable quick field wiring and maintenance. Semi-flush mounting and a compact footprint simplify panel design and service access in challenging environments, lowering lifecycle costs. Extensible I/O and synchronization: I/O options include IRIG-B Trip Coil Monitor and URTD interfaces, enabling precise time synchronization and advanced trip testing. Zone selective interlocking support further enhances selectivity and reduces arc-flash risk in large power systems.

FAQs
Yes. The EGR-5000-2A0BB0 supports RS-485 communications using Modbus RTU or DNP3 RTU, enabling straightforward integration with common SCADA platforms. With 16 digital inputs and 9 outputs, you can consolidate protection logic in a single device, reducing panel wiring and simplifying field wiring during retrofit or new installations.
Core specs include 19–300 Vdc and 40–250 Vac power support, 50/60 Hz operation, 16 digital inputs, 9 outputs, and phase current options of 5 A and 1 A. The device provides voltage, current, differential, power protection and metering, plus RS-485-based Modbus RTU or DNP3 RTU communication for reliable protection coordination.
Yes, it is designed for generator protection in demanding environments. Its conformal coating increases reliability in moisture-prone or dusty spaces, while 16 DI/9 DO I/O supports elaborate protection schemes and interlocks. Time-sync options (IRIG-B) and zone selective interlocking enhance protection coordination, contributing to reduced outage duration and improved availability.
Compliance status is region-specific and must be confirmed with Eaton. The datasheet indicates 'Compliances: Contact Manufacturer,' so check applicable regulatory marks, IP/ enclosure ratings, and SIL requirements with Eaton or a local distributor to ensure full conformity for the target installation site.
Consolidating protection, metering, and interface functions into a single device reduces panel space and wiring, lowering installation and maintenance complexity. The conformal coating improves field reliability, while remote diagnostics via RS-485 enable proactive maintenance. Overall, expect lower lifecycle costs through fewer external modules and faster fault resolution.
