FAQs
The EGR-5000-2B1EB0 uses semi-flush mounting and has removable terminals, which simplifies wiring, testing, and field servicing. The wide power-supply range (19-300 Vdc and 40-250 Vac) supports diverse site configurations, easing retrofits and new builds. This flexibility reduces installation time and limits the need for special adapters.
It offers 8 digital inputs, 9 digital outputs, 2 analog inputs, and 2 analog outputs, plus capabilities like Trip Coil Monitor, IRIG-B time interface, URTD interface, and a Sensitive Ground Input. This combination supports comprehensive protection, metering, event signaling, and precise time synchronization essential for reliable generator operation and coordination with the control system.
Yes. The relay supports PROFIBUS-DP over D-Sub/RS-485, enabling robust, scalable communication with PLCs and SCADA systems. This facilitates centralized protection logic, faster data exchange, and easier integration into existing automation architectures.
Compliances are provided by the manufacturer and depend on regional requirements. Eaton can supply current CE, SIL, and IP-related documentation upon request. For project-specific certifications, contact Eaton’s technical support to obtain the latest compliance package and test reports.
The relay’s conformal coating and rugged construction reduce environmental wear, lowering maintenance intervals. Removable terminals simplify diagnostics and replacements, saving service time. A one-year warranty (or 18 months from shipment, per Eaton policy 25-000) provides a baseline for total cost of ownership and downstream ROI through reduced downtime and improved reliability.
