Quick Summary

Eaton transformer relay protects transformer assets by monitoring conditions and triggering trips in substations and industrial power systems. Engineers struggle to coordinate protection across feeders and maintain reliable communication with remote devices. Compliance details like CE, SIL, and IP ratings are determined by Eaton and can vary by market; verify with the manufacturer. This relay supports Modbus RTU or DNP3 RTU over fiber, enabling robust monitoring and faster MTTR, while staying compatible with existing protection schemes. By combining differential protection and metering, it delivers actionable data for procurement and maintenance teams, improving uptime and reducing field visits.

Eight digital inputs and nine outputs, plus two current sensing inputs, enable advanced protection logic with minimal wiring. This reduces panel complexity and wiring costs while enabling precise tripping and signaling. Ideal for transformer protection panels in substations and large industrial facilities where fast, reliable I/O is essential. Wide power supply range of 19-300 Vdc and 40-250 Vac, with 50/60 Hz operation, ensures compatibility with existing plant power rails. This tolerance lowers installation risk and eliminates the need for multiple adapters. In practice, engineers can deploy the relay across diverse locations, including outdoor or harsh environments, with minimal rework. Communications via Modbus RTU or DNP3 RTU over fiber optic ST provides robust, noise-immune links to SCADA and protection systems. The business impact is improved visibility and faster fault localization, reducing MTTR. This compatibility helps retrofit or expand protection without replacing existing networks. Differential protection, current protection, and metering with zone selective interlocking (2 zones) enable precise fault isolation and coordinated protection. The outcome is improved selectivity and reduced system-wide outages. This configuration suits heavy-duty transformers in industrial facilities and utility networks, enabling precise protection coordination with existing relays. Conformal coating on circuit boards and removable terminals enhance reliability in challenging environments. The rugged design supports long service life with predictable maintenance windows. In practice, maintenance teams benefit from easier field service and durable field installations, while URTD interface and IRIG-B options support specialized monitoring and time synchronization.

FAQs

The unit offers removable terminals and eight digital inputs with nine outputs, simplifying panel wiring and layout. Its wide power range (19–300 Vdc, 40–250 Vac) supports diverse plant voltages, while the fiber-based Modbus RTU communication minimizes noise and installation complexity in crowded switchgear rooms. Plan for compatible mounting space and ensure fiber connectivity to the control network.
Key specs include eight digital inputs, nine outputs, two current-sensing inputs (5 A and 1 A), power supply range 19–300 Vdc and 40–250 Vac, and 50/60 Hz operation. The device supports differential protection, current protection, and metering, with zone selective interlocking. Verify compatibility with your SCADA/RTU interface (Modbus RTU or DNP3 RTU) and ensure the fiber optic link meets distance and environment requirements.
Yes, it is designed for demanding environments with conformal coating on the circuit boards, and removable terminals for serviceability. The wide voltage and frequency ranges support diverse outdoor and indoor installations, while the fiber-based communications reduce susceptibility to EMI. For outdoor use, confirm enclosure rating, service access, and required environmental specifications with Eaton.
