Flexible I/O and protection logic enables precise protection and metering with minimal external wiring. This reduces panel complexity, lowers wiring errors, and speeds commissioning in OEM equipment and field installations. Practical applications include transformer protection schemes in substations and protection relays for OEM transformer packages. Global power compatibility comes from a wide power-supply range and 50/60 Hz support. This flexibility minimizes regional variants, accelerates deployment across sites with diverse mains, and simplifies procurement for multinational projects. Removable terminals and projection mounting streamline installation, maintenance, and upgrades, reducing downtime and enhancing retrofit speed in aging facilities and new builds alike. Advanced communications and time synchronization features—IRIG-B Trip Coil Monitor, Sensitive Ground Input, URTD Interface, and Modbus/DNP3 TCP over fiber—enable robust remote monitoring and precise fault correlation across plant networks. Conformal-coated circuit boards and zone-selective interlocking with differential protection improve environmental resilience and selectivity, lowering maintenance costs and boosting uptime in harsh industrial environments. Compatibility with the Eaton ETR-4000 base relay provides a familiar platform for service and spare parts, while the 8/9 I/O configuration supports scalable protection and metering for transformer assets.

FAQs

The unit uses removable terminals and projection mounting to simplify field wiring and assembly. Plan for the 8 digital inputs and 9 outputs, 2 current sensing inputs, and 19-300 Vdc / 40-250 Vac power supply. Consider space for panel mounting and ensure proper labeling of I/O for maintenance and future upgrades.
Key specs include 50/60 Hz operation, dual power ranges (19-300 Vdc and 40-250 Vac), 8 digital inputs, 9 digital outputs, 2 current sensing inputs, and 5A/1A phase current options. These support differential protection, metering, and robust fault detection within transformer networks.
Yes, the relay supports Zone Selective Interlocking with ZSI capability (listed as 2 in the configuration) to improve selective tripping. This reduces misoperations and improves restoration times in complex motor and transformer protection schemes.
Compliances are specified as contact the manufacturer for certification details; warranty is Eaton’s policy: 25-000, one year from installation or eighteen months from shipment, whichever occurs first. Confirm regional regulatory requirements and local service options with Eaton during procurement.
Common use cases include transformer protection, differential protection, and remote monitoring in OEM equipment and substations. ROI benefits come from faster fault detection, improved protection selectivity, reduced downtime, streamlined commissioning with PowerPort-E workflows, and lower maintenance costs due to rugged, conformal-coated boards and modular I/O.
