Quick Summary

The Eaton transformer relay protects and monitors transformer assets in industrial power systems. Engineers often struggle to harmonize protection logic, remote diagnostics, and configuration across multiple devices in busy switchgear. Formal certifications such as SIL, CE, or IP ratings aren’t listed in the data; please confirm with the manufacturer for specifics. This device supports Modbus RTU or DNP3 RTU over RS-485, with eight digital inputs, nine digital outputs, and two current-sensing inputs, enabling scalable protection schemes. By combining robust communication, broad power-supply ranges, and conformal-coated circuitry, it reduces wiring complexity and speeds commissioning, delivering clearer fault visibility and lower lifecycle costs for transformer protection projects.

Eight digital inputs, two current sensing inputs, and nine outputs provide a compact yet capable I/O platform for protection logic, metering, and control. The business impact is reduced panel wiring, faster commissioning, and easier fault diagnosis by keeping critical signals local to the relay. This is ideally applied to transformer protection and smart feeder coordination in substations and manufacturing campuses. The Modbus RTU or DNP3 RTU over RS-485 interface enables seamless integration with SCADA systems, bringing centralized visibility and simplified configuration across multiple devices in a plant. The result is lower integration costs and faster response times to faults. A wide power-supply range (19-300 Vdc, 40-250 Vac) and 50/60 Hz compatibility support retrofit to diverse installations, reducing inventory variety and easing field deployment. Conformal-coated circuit boards improve reliability in harsh environments, while removable terminals and semi-flush mounting simplify installation and future upgrades. The I/O options, including IRIG-B, URTD Interface, Sensitive Ground Input, and Trip Coil Monitor, provide flexibility for sophisticated protection schemes and testing protocols. Overall, this combination supports reliable transformer protection with scalable expansion, minimizing downtime and maintenance overhead while meeting industry expectations for modern protection relays.
