Eaton Specification Sheet - ETR-4000-2A2DB1
8 digital inputs, 9 digital outputs, and 2 current sensing inputs provide comprehensive transformer protection and metering at the device edge. This combination enables precise fault detection and flexible control logic, reducing reliance on multiple standalone relays and streamlining wiring in control cabinets. The design supports transformer protection schemes and differential protection, making it ideal for OEM equipment and substations. Profibus-DP over fiber optic ST ensures reliable fieldbus communication in electrically noisy environments, reducing miscommunication and enabling faster diagnostics across the protection network. Power supply range of 19-300 VDC and 40-250 VAC simplifies retrofits and new builds, accommodating a wide variety of control voltages. Conformal coating protects sensitive circuitry in harsh environments, increasing uptime in dust, humidity, or splash-prone locations. I/O options including IRIG-B, Trip Coil Monitor, URTD Interface, and Sensitive Ground Input enable advanced protection strategies and precise timing. Removable terminals and projection mounting facilitate quick installation and maintenance, reducing commissioning time and field labor.

FAQs
The ETR-4000-2A2DB1 is designed for Profibus-DP over fiber optic ST, enabling reliable fieldbus communication in electrically noisy environments. With 8 digital inputs, 9 digital outputs, and 2 current sensing inputs, it integrates easily into transformer protection schemes and supports zone selective interlocking. This compact, centralized protection approach reduces wiring complexity and speeds diagnostics, improving overall system availability.
Key electrical specs include a wide power-supply range of 19-300 VDC or 40-250 VAC, with 50/60 Hz operation. The unit features two current sensing inputs, 5 A and 1 A phase currents, eight digital inputs, and nine digital outputs. These capabilities support comprehensive protection, metering, and control within a single relay, simplifying integration with existing equipment.
Yes. Its projection mounting and removable terminals simplify installation in existing control cabinets. The wide power range and Profibus-DP communications support easy integration with legacy PLCs and SCADA. Additional I/O options such as IRIG-B and Trip Coil Monitor enable advanced protection schemes, making it a viable upgrade path for aging transformer protection networks.
Maximize reliability with conformal-coated circuit boards that resist moisture and dust, and leverage Profibus-DP over fiber to minimize electrical noise issues. Ensure proper enclosure protection and configure zone interlocking per plant protection philosophy. The removable terminals and projection mounting also reduce maintenance time during commissioning and routine servicing.
consolidating protection, metering, and control into a single unit reduces panel space, wiring, and spare parts. Faster commissioning and diagnostics lower downtime, while robust communications and modular I/O enable scalable protection as installations grow. A one-year Eaton warranty provides additional risk mitigation, supporting predictable maintenance costs over the asset lifecycle.
