Quick Summary

The Eaton transformer relay is a robust protection device for industrial power networks. It delivers protective intelligence by monitoring transformer parameters and initiating appropriate actions to prevent faults. In practice, engineers often struggle with integrating multiple signals, achieving fast fault isolation, and simplifying wiring in dense panel layouts. This model consolidates eight digital inputs, nine digital outputs, and two current sensing inputs into a single unit with removable terminals for easier field upgrades. It supports Modbus/RTU over RS-485 and Modbus TCP over Ethernet, aiding modern control rooms, while its power ranges of 19–300 Vdc and 40–250 Vac simplify power planning. Exact certifications should be confirmed with Eaton, but the device is designed to meet typical industry expectations for transformer protection relays in 50/60 Hz systems, aligning with broader automation goals.

FAQs

Begin with the semi-flush mounting setup and secure the unit to the panel. Connect eight digital inputs, nine digital outputs, and two current sensing inputs to the corresponding field devices. Use removable terminals for quick wire termination, then configure power supply within 19–300 Vdc or 40–250 Vac. Establish communication via RS-485 Modbus RTU or Ethernet Modbus TCP to integrate with your PLC/SCADA system.
The relay supports current protection and metering, differential protection, zone selective interlocking, and Trip Coil Monitor. In fault conditions, the device executes protective logic to trigger appropriate tripping signals, isolates the transformer, and provides diagnostic data via Modbus TCP/RTU, enabling rapid operator action and minimized fault propagation in transformer circuits.
Yes. With 50/60 Hz operation, 8 DI / 9 DO I/O, RS-485 and Ethernet communications, and options like Sensitive Ground Input and IRIG-B, the ETR-4000-2A2IB0 is well-suited for transformer protection in both substations and motor control centers. Its modular I/O and robust mounting support reliable integration into standard industrial architectures.
Compliances are listed as Contact Manufacturer, so verify exact regulatory certifications (for your region) such as safety, EMC, and environmental ratings with Eaton. Confirm any SIL/CE/UL or IP rating requirements for your installation and ensure the unit meets your facility's compliance and safety documentation before deployment.
Maintenance benefits include reduced field visits through improved remote diagnostics via RS-485 and Ethernet, and the removable terminals simplify upgrades and servicing. ROI drivers include shorter downtime during fault conditions, faster fault isolation, and lower wiring complexity from a single integrated relay, all contributing to higher equipment availability and lower lifecycle costs.
