Eaton Generator Relay EGR-5000-2A1FA1 - Modbus RTU
Part Number: EGR-5000-2A1FA1
Quick Summary
An Eaton generator relay provides robust generator protection and control for industrial standby power systems. Many engineers struggle to harmonize protection settings with remote monitoring and cross-network communication. Compliance details can vary by region, so confirming certifications such as SIL readiness, CE marking, and IP-rated enclosures with Eaton ensures the protection scheme meets site requirements. This model supports Modbus RTU and DNP3 RTU over fiber, URTD Interface, IRIG-B time synchronization, and a Trip Coil Monitor, delivering precise protection logic. The combination of flexible IO, scalable protection algorithms, and secure communications translates to faster commissioning, reduced wiring complexity, and improved operational visibility for OEMs and end users.

FAQs
Install the EGR-5000-2A1FA1 as a shielded protection relay within the generator control cabinet, using the 16 digital inputs and 9 digital outputs to map protection logic to local alarms and interlocks. Take advantage of removable terminals for quick field wiring and the projection mounting method for secure panel installation. Ensure the power supply is within the 19-300 VDC / 40-250 VAC range and verify 50/60 Hz operation to match the generator set. For SCADA integration, configure Modbus RTU or DNP3 RTU over fiber and verify IRIG-B time synchronization if time-stamped events are required.
The relay supports differential protection, current protection and metering, power protection and metering, and voltage protection and metering. This comprehensive set enables precise fault detection, protection coordination, and accurate monitoring of generator performance. Zone selective interlocking helps isolate faults quickly, reducing impact on upstream equipment and improving reliability in both standby and prime power configurations.
Yes, the EGR-5000-2A1FA1 is designed for generator protection in critical applications. Its support for Modbus RTU and DNP3 RTU over fiber, URTD Interface, IRIG-B time sync, and Trip Coil Monitor enables precise protection sequencing, robust monitoring, and time-stamped event logging essential for mission-critical environments and grid-tacing requirements.
Compliance details for the EGR-5000-2A1FA1 are provided by Eaton. Certification status such as CE marking, SIL readiness, IP ratings, and other regional approvals can be confirmed with Eaton directly or through the product datasheet, ensuring the relay meets your local regulatory and reliability requirements before installation.
The unit comes with Eaton’s standard warranty (one year from installation or 18 months from shipment, whichever occurs first) and supports remote monitoring via fiber-based Modbus/DNP3.
