The ETR-4000 family delivers eight digital inputs and nine outputs, enabling rich I/O without the need for extensive external modules. This translates to faster wiring, fewer fault points, and streamlined commissioning, which lowers installation costs while improving protection reach for transformer installations in panel-built machinery and substations. With Profibus-DP over D-Sub / RS-485 connectivity, it integrates easily into PLC/SCADA networks, reducing configuration time and enabling robust remote monitoring and diagnostics for plant-wide visibility. The dual power-supply range of 19-300 Vdc and 40-250 Vac supports diverse supply environments, simplifying retrofits and new builds alike and ensuring reliable operation across multiple sites. Zone selective interlocking (two zones) accelerates fault isolation, minimizing equipment damage and downtime in multi-transformer configurations common to manufacturing lines and power distribution cages. The device also provides differential protection, current protection and metering, delivering precise fault detection and energy data for tighter protection schemes and improved energy management. Removable terminals and a semi-flush mounting method ease installation and future servicing, reducing maintenance windows and enabling quick upgrades in evolving control architectures. With 50/60 Hz operation, 8 DI/9 DO, and a compact yet capable form factor, the ETR-4000-2A1EA0 is well suited for OEMs seeking a dependable transformer protection relay that integrates with existing Profibus/RS-485 networks and minimizes total cost of ownership.

FAQs

Begin by planning for the device’s semi-flush mounting and ensure space for wiring. Use the removable terminals to connect the eight digital inputs and nine outputs, then connect the power supply within the 19-300 Vdc or 40-250 Vac ranges. For fieldbus, attach the Profibus-DP RS-485 connection via the D-Sub interface. Verify clearances per Eaton installation guidelines, then perform a commissioning sequence using the base relay settings (ETR-4000) and the system controller to confirm correct fault detection and metering behavior.
The unit provides differential protection and current protection with metering capabilities, enabling precise fault detection. It supports two zone selective interlocking regions to speed up fault isolation in multi-transformer configurations. With 50/60 Hz operation and 5 A / 1 A phase-current options, it accommodates a range of transformer sizes and connection schemes, while the 8 DI / 9 DO I/O set enables integrated protection coordination with plant controllers.
Yes, the ETR-4000 uses Profibus-DP over D-Sub / RS-485 for fieldbus communication. Configuration is performed through the base relay interface and compatible Eaton or third-party PLC software. Ensure the RS-485 termination and addressing align with your PLC network; consult Eaton’s specification sheet and installation guide for step-by-step setup and diagnostic wiring checks to ensure reliable data exchange and monitoring.
Key considerations include ensuring compatible power supply (DC or AC), matching the 8 digital inputs and 9 outputs to your control strategy, and confirming Profibus-DP network availability. The unit supports semi-flush mounting with removable terminals, simplifying retrofits in existing panels. Verify that your PLC or DCS supports Profibus-DP over RS-485 and review the Eaton datasheet for any revision-specific wiring changes.
ROI benefits arise from consolidated protection I/O, reduced external module count, and faster fault isolation thanks to zone selective interlocking. The device’s metering and differential protection enhance fault detection accuracy, lowering downtime and sparing equipment from collateral damage. A standard one-year warranty supports ongoing maintenance planning, while the manufacturer’s documentation helps streamline audits and compliance validation.
