Quick Summary

Eaton transformer relay is a protection device that delivers transformer protection and monitoring for power networks and OEM equipment. Engineers often face nuisance trips and slow fault isolation when protection schemes aren’t tightly coordinated across devices. Compliances are provided by the manufacturer; confirm CE, SIL, or IP requirements with Eaton as needed. The ETR-4000-2A0HB0 supports IEC 61850, M-Bus TCP, and DNP3 TCP/UDP over Ethernet, enabling seamless integration into modern substation automation and remote monitoring workflows, while offering wide input ranges and modular I/O to support scalable protection architectures.

The 8 digital inputs and 9 digital outputs enable robust signaling and interlock control, improving fault containment and reducing operational risk in transformer protection schemes. This translates to quicker isolation during faults and lower risk of collateral damage, which is critical in substations and industrial facilities. The dual power-supply range of 19-300 Vdc and 40-250 Vac provides flexible installation across diverse plant environments, reducing wiring complexity and guarding against supply-voltage issues. With 2 current sensing inputs and differential protection capabilities, operators gain precise fault detection and metering to support asset health monitoring and energy management goals. The I/O options include Trip Coil Monitor, URTD Interface, and IRIG-B time synchronization, which streamline protection coordination and time-stamped event logging for post-event analysis. Conformal-coated circuit boards and removable terminals simplify field maintenance and enhance reliability in harsh environments, while semi-flush mounting speeds up retrofits and panel installations. The 61850, M-Bus TCP, and DNP3 TCP/UDP communications ensure quick SCADA integration, reducing commissioning time and enabling remote diagnostics, trending, and alarm management. With Eaton’s base relay, the ETR-4000 series provides a proven foundation for transformer protection, metering, and monitoring in both new builds and refurbishments, aligning with industry standards and customer-specific protection philosophies.
