Eaton ETR-5000-2A0FB0 Transformer Relay - Fiber Optic
Part Number: ETR-5000-2A0FB0
Quick Summary
Eaton transformer relay is a protective device for transformer protection and monitoring in power systems. Engineers struggle to integrate protection relays that support multiple protocols and survive demanding industrial environments. Certification details are provided by the manufacturer, with verify CE, SIL, and IP ratings in Eaton’s datasheets to ensure compliance as your project requires. This device combines transformer protection with Modbus RTU or DNP3 RTU communication over fiber, helping you centralize monitoring and diagnostics. The result is faster fault isolation, improved asset uptime, and streamlined asset management for OEMs and utilities.

Removable terminals simplify field installation and maintenance, reducing commissioning time and minimizing downtime during retrofits. The Modbus RTU or DNP3 RTU over fiber optic interface delivers galvanic isolation and robust remote monitoring, enabling seamless SCADA integration for transformers in substations and data centers. The wide power supply range of 19-300 Vdc / 40-250 Vac and dual 50/60 Hz operation eliminates power mismatches in multi-site deployments, supporting reliable protection across diverse facilities. Eight digital inputs and nine digital outputs, plus two current sensing inputs, provide flexible control and status reporting while reducing the need for additional protective relays in complex protection schemes. I/O options such as Trip Coil Monitor, URTD interface, and IRIG-B enable precise coordination with other protection layers and event timing. Conformal coating and semi-flush mounting improve reliability in harsh environments and simplify service in outdoor or installation in compact switchgear. Zone selective interlocking with two zones supports selective tripping, lowering energy losses and improving system reliability. Eaton’s warranty and global support help keep total cost of ownership low, translating to predictable maintenance budgets and faster return on investment.

FAQs
Begin with mounting the relay using its semi-flush method and connect the removable terminals. Power the unit from 19-300 Vdc or 40-250 Vac, then wire the 8 digital inputs, 9 digital outputs, and 2 current sensing inputs. Configure Modbus RTU or DNP3 RTU over fiber optic ST for secure SCADA integration, and verify the Trip Coil Monitor and IRIG-B options as needed for precise timing and control.
The ETR-5000-2A0FB0 supports Modbus RTU or DNP3 RTU over fiber optic ST, providing galvanic isolation and robust remote monitoring. This enables seamless integration with existing SCADA and protection schemes while preserving data integrity in harsh environments.
Yes. The device supports zone selective interlocking with two zones, enabling selective tripping to minimize disturbance and energy losses. This feature is particularly valuable in large feeders and substation protection architectures.
