Eaton generator relay EGR-5000-2A0EA0 - Profibus-DP/RS-485
Part Number: EGR-5000-2A0EA0
Quick Summary
Eaton generator relay protects standby and prime power generators, enabling reliable automatic transfer and fault detection. Engineers often struggle with integrating protection, signaling, and communication in a compact panel. Note: explicit certifications such as SIL, CE, or IP ratings are not listed in this spec; consult Eaton datasheets for current approvals and regional compliance. With broad input ranges and multi-communication options, it delivers scalable protection that reduces downtime and simplifies panel design. This product is ideal for generator protection relays in industrial facilities, data centers, and remote power installations. Its 16 digital inputs and 9 outputs support complex protection schemes while maintaining a compact footprint. Early fault detection with differential protection and zone selective interlocking helps prevent cascading outages.

Generous digital I/O and integrated protection: The EGR-5000-2A0EA0 provides 16 digital inputs, 9 digital outputs, and 2 current-sensing inputs, enabling comprehensive protection logic within a single relay. Business impact includes reduced panel wiring, fewer devices to coordinate, and lower installation costs, while ensuring accurate fault isolation in generator systems. In industrial applications like factories, data centers, and remote sites, this consolidation translates to faster commissioning and easier maintenance. Robust communications and integration: PROFIBUS-DP over D-Sub / RS-485, plus an IRIG-B URTD interface and a Trip Coil Monitor, streamline control system integration, enable remote diagnostics, and shorten engineering cycles for power management systems. Application spans automation-heavy facilities where fast signaling and centralized monitoring matter. Flexible power and mounting: Supports 19-300 Vdc and 40-250 Vac power, 50/60 Hz operation, removable terminals, and semi-flush mounting, allowing global installation and simplified panel upgrades. This flexibility reduces field wiring and speeds up retrofits in OEM and retrofit projects. Protection fidelity and selectivity: Voltage, current, power metering, differential protection, and zone selective interlocking (1) improve coordination and minimize outage impact. For utilities and critical-load installations, this means faster fault clearance and reduced downtime. Lifecycle support: The device ships with Eaton’s standard warranty and is designed for long-term serviceability, helping lower total cost of ownership and supporting proactive maintenance planning for facilities and OEM integrators.

FAQs
Plan for the relay’s semi-flush mounting and removable terminals to simplify retrofits. Ensure panel space fits a unit approximately 9.72 x 8.7 x 8.06 inches and accommodates 16 digital inputs and 9 outputs. Verify supply compatibility with 19-300 Vdc or 40-250 Vac and plan for PROFIBUS-DP/RS-485 wiring. Reference the base EGR-5000 platform and Eaton datasheets for mounting guidelines and cabling requirements.
It provides Voltage Protection and Metering, Power Protection and Metering, Current Protection and Metering, and Differential Protection across 16 digital inputs and 9 outputs. Zone Selective Interlocking (ZSI) enhances selectivity, while 5A/1A phase currents and a Trip Coil Monitor improve fast, coordinated fault clearance. These features support reliable generator protection in dynamic load conditions.
The spec lists Removable terminals and a robust protection feature set, with operation across 50/60 Hz and a wide voltage range. The datasheet notes Conformal coating as None, and explicit environmental ratings (IP/CE/SIL) are not listed here. For harsh environments, confirm regional approvals and consider enclosure protection, installation practices, and remote monitoring via PROFIBUS-DP for diagnostics.
Compliances are listed as Contact Manufacturer, with the Eaton datasheets providing the current regional approvals. To ensure CE, SIL, IP ratings, or other certifications are met for your facility, consult the latest Eaton specifications sheet and regional compliance documents before procurement or installation.
The product carries Eaton’s standard warranty: one year from installation or 18 months from shipment, whichever occurs first. A single-relay solution reduces wiring and inventory, lowers maintenance labor, and streamlines spare parts management, contributing to a lower total cost of ownership for OEMs and facilities teams.
