Quick Summary

Eaton transformer relay protects transformers and monitors faults in industrial power systems. Engineers often face slow fault diagnosis and complex wiring when upgrading protection schemes across legacy installations. Certification considerations include CE compliance for European installations and UL/IEC references commonly cited in protective-relay datasheets; verify exact approvals from Eaton's datasheet. With 8 digital inputs, 9 outputs, and Modbus/DNP3 TCP communication, it integrates cleanly with modern SCADA and protection schemes, delivering faster fault isolation and better asset protection. This device supports transformer protection and metering functions with differential protection and meter inputs, enabling precise fault detection. The combination simplifies installation, enables future upgrades, and supports predictable maintenance windows.

FAQs

The device is designed for universal compatibility across the specified DC and AC ranges. Begin by mounting the unit in a projection-compatible panel, connect removable terminals per the wiring diagram, and assign the 8 digital inputs and 9 digital outputs to the process signals and interlocks. Use the IRIG-B and Trip Coil Monitor where required for enhanced protection schemes. Ensure proper grounding and verify the Modbus/DNP3 TCP network configuration for SCADA integration.
Key specs include the power supply range (19-300 Vdc / 40-250 Vac) and the operating frequency (50/60 Hz). The unit provides 8 digital inputs and 9 digital outputs, with removable terminals for ease of maintenance. It supports Modbus TCP and DNP3 TCP over fiber for industrial communications, and includes current sensing inputs (2) for protection logic. Confirm the exact configuration from the Eaton datasheet prior to installation.
Yes. With eight digital inputs, nine digital outputs, and flexible power options, it accommodates a wide range of protection and metering tasks, including zone selective interlocking and fast fault isolation. Its modular I/O and robust communication options simplify integration with existing SCADA systems, reducing downtime during fault events and easing future expansions.
Compliances are provided by the manufacturer; local approvals vary by region. Typical transformer protection relays reference CE marks and UL/IEC standards, but you should verify exact approvals on Eaton’s datasheet or contact Eaton directly to obtain the region-specific certification matrix for your installation site.
The device reduces maintenance downtime through removable terminals that simplify field servicing and upgrades. The integrated protection and metering reduce unplanned outages by enabling faster fault diagnosis. Additionally, SCADA integration via Modbus/DNP3 TCP enables centralized monitoring, improving asset uptime and potentially lowering total cost of ownership.
