Eaton ETR-4000-2A3DA1 Transformer Relay - Profibus-DP
Part Number: ETR-4000-2A3DA1
Quick Summary
The Eaton transformer relay ETR-4000-2A3DA1 is a high-performance protection device for transformer banks in industrial power systems. It integrates protection, monitoring, and communication in a single unit to simplify panel design and commissioning. Engineers often struggle with coordinating protection logic, diagnostics, and field wiring across multiple devices; this model reduces complexity with eight digital inputs, nine outputs, and Profibus-DP connectivity. Compliance details vary by market, so confirm regional approvals like CE/UL and any IP considerations with Eaton. For operations, the value lies in tight protection orchestration, reduced downtime, and streamlined maintenance, while preserving flexibility for differential protection, current protection, and metering capabilities.

FAQs
Installation is streamlined by removable terminals and a projection mounting method, allowing easy panel integration and future serviceability. With 8 digital inputs and 9 outputs, plan the wiring to support differential protection, current protection, and metering while leveraging Profibus-DP communication for centralized control and monitoring.
It combines differential protection, current protection, and metering inputs with 2 current sensing channels and 8/9 I/O endpoints. Its zone selective interlocking capability helps minimize disturbance during faults, while Profibus-DP connectivity enables rapid data exchange with PLCs and SCADA systems for improved reliability.
The unit supports Profibus-DP over fiber optic ST, enabling robust field network communication and remote diagnostics. This is complemented by monitoring capabilities through its integrated protection features, allowing operators to access fault and status information quickly from the supervisory system.
Compliance details are provided by the manufacturer; regional approvals such as CE and UL may apply depending on the market. Verify the exact certifications with Eaton prior to purchase or installation to ensure alignment with local electrical codes and safety requirements.
By consolidating protection, monitoring, and communication in a single device, the relays reduce panel space, wiring, and commissioning time. This minimizes downtime during maintenance, lowers the total cost of ownership, and supports faster fault isolation, ultimately delivering measurable improvements in reliability and plant uptime.
