Quick Summary

Eaton transformer relay protects transformers and monitors critical protection functions for industrial power systems. Design teams often struggle to integrate protection logic with Modbus RTU or DNP3 RTU over RS-485 while keeping fault isolation fast and reliable. Certification visibility for this model isn’t published; confirm SIL, CE, or IP ratings with Eaton as needed. With eight digital inputs, nine outputs, and dual power ranges of 19–300 Vdc and 40–250 Vac, this device enables scalable protection and metering across equipment fleets, reducing downtime and simplifying commissioning in substations and industrial plants.

Communication interfaces are designed for seamless integration; Modbus RTU or DNP3 RTU over RS-485 enables reliable plant-wide monitoring and remote control, reducing wiring complexity and speeding up commissioning while improving data accuracy for transformer protection assets. This directly lowers operational risk and supports SCADA interoperability, essential for large substations and OEM equipment deployments. The 8 digital inputs and 9 outputs provide ample I/O headroom to implement advanced protection schemes without expanding cabinet footprint, delivering tangible space and cost savings while enhancing fault isolation capabilities. The 2 current sensing inputs support differential and metering functions, enabling precise protection coordination and power quality monitoring, which reduces false trips and improves energy management. Power is flexible across 19–300 Vdc and 40–250 Vac with 50/60 Hz compatibility, simplifying retrofit projects and minimizing electrical infrastructure rewiring. The unit’s projection mounting and removable terminals streamline installation and service, minimizing downtime during upgrades while maintaining robust field reliability. Conformal coating further enhances resilience in harsh industrial environments, supporting long-term performance and reducing maintenance costs. The ETR-4000 base relay compatibility and options for Trip Coil Monitoring, URTD interface, and IRIG-B time synchronization provide a scalable path for future protection enhancements, aligning with evolving grid and plant automation standards.

FAQs

Plan for projection mounting and removable terminals to simplify retrofits. Ensure panel depth accommodates an 8.06 in length and 9.72 in width footprint. Leverage base compatibility with ETR-4000 and use the conformal-coated circuit boards in harsh environments. Confirm wiring practices align with RS-485 Modbus or DNP3 RTU interfaces to minimize interference and optimize commissioning time.
Key specs include 8 digital inputs and 9 outputs with 2 current sensing inputs for differential protection and metering. The power supply range covers 19–300 Vdc and 40–250 Vac, operating at 50/60 Hz. Communication is via Modbus RTU or DNP3 RTU over RS-485, enabling robust SCADA integration and fast fault isolation in transformer protection schemes.
Yes. It provides transformer protection, metering, and remote communication suitable for substations and industrial plants. Its 8/9 IO and Modbus/DNP3 interfaces support scalable protection coordination, while the 50/60 Hz compatibility and wide power ranges ease integration with existing electrical gear and control systems in both new builds and retrofit projects.
