8 digital inputs and 9 digital outputs enable comprehensive control and monitoring within a single relay. This consolidation reduces panel wiring, saves space, and minimizes wiring errors during installation. In transformer protection applications, the dense I/O simplifies sequencing, alarms, and interlocks. Two current sensing inputs support precise protection and metering, with phase currents selectable at 5A or 1A. This capability improves fault discrimination and reduces nuisance trips, essential in transformer protection schemes. Power supply range of 19-300 Vdc / 40-250 Vac with 50/60 Hz operation, plus removable terminals and semi-flush mounting, offers flexible installation and straightforward field wiring. Advanced I/O options and communications streamline integration with IRIG-B timing, Trip Coil Monitor, Sensitive Ground Input, URTD Interface, and Modbus/DNP3 TCP over LC duplex fiber Ethernet. Conformal coating enhances reliability in harsh environments, and a one-year warranty (or 18 months from shipment) reduces maintenance risk. Removable base compatibility and Eaton support simplify upgrades within existing protection architectures, ensuring quick commissioning and long-term compatibility with SCADA and protection schemes.

FAQs

Ensure the relay is mounted semi-flush with removable terminals for simplified wiring. Wire 8 digital inputs and 9 outputs, connect 2 current sensing inputs to appropriate CTs (5A/1A), and supply 19-300 Vdc or 40-250 Vac at 50/60 Hz. Use the provided connection diagrams and conformal coated boards to maintain reliability in industrial environments. The unit also supports Modbus/DNP3 TCP over LC fiber for panel-to-plant communications.
Key specs include 5A/1A phase current sensing, 8 inputs and 9 outputs, a power supply range of 19-300 Vdc and 40-250 Vac, and 50/60 Hz operation. It supports differential protection and current protection metering, with Modbus/DNP3 TCP communications and IRIG-B timing to ensure precise protection coordination and SCADA interoperability.
Yes. Its 8/9 I/O, 2 current sensing inputs, and support for Modbus/DNP3 TCP over fiber enable integration with distribution protection schemes and SCADA systems. The device’s flexible power options and mounting, together with differential protection features, help meet coordination requirements and minimize fault impact in feeder configurations.
Compliances are listed as 'Contact Manufacturer' on the data sheet, and typical Eaton E-Series relays support CE marking and SIL configurations depending on installation. IP ratings depend on enclosure design; verify the specific enclosure for your environment. Always confirm applicable standards with your compliance team prior to procurement and deployment.
The product carries Eaton’s warranty policy of one year from installation or eighteen months from shipment, whichever occurs first. The relay’s integrated I/O, removable terminals, and conformal coating reduce downtime and maintenance costs, while fiber-enabled communications and scalable protection features help lower long-term total cost of ownership in transformer protection applications.
