Quick Summary

The Eaton ETR-5000-2A1FB1 transformer relay is a sophisticated protection and monitoring device designed for transformer assets in industrial power systems. Engineers face challenges coordinating protection schemes and diagnosing faults across large electrical networks, often under tight downtime windows. While regulatory certifications vary by region, typical requirements include CE marking, SIL considerations, and appropriate IP ratings; confirm with Eaton for your installation. With Modbus RTU or DNP3 RTU over fiber, this relay enables reliable remote diagnostics, while eight digital inputs and nine outputs support scalable protection configurations. Together, these features translate to reduced downtime, improved asset protection, and clearer insight into metering and protection performance across 19-300 Vdc and 40-250 Vac systems.

FAQs

The unit uses removable terminals and a projection mounting method for straightforward panel integration. With 8 digital inputs and 9 digital outputs, it supports flexible wiring schemes, while the modular I/O options allow you to tailor the setup to the transformer protection strategy without rewiring existing panels.
Key features include differential protection and comprehensive metering (voltage, current, power) within a single device, 2 current sensing inputs, and zone selective interlocking. Combined with fiber-based Modbus RTU or DNP3 RTU communications, it delivers fast fault isolation and reliable remote diagnostics in demanding environments.
Yes. The ETR-5000-2A1FB1 supports Modbus RTU and DNP3 RTU communications over fiber optic ST, providing isolated, high-reliability signaling between the relay and control systems. This setup improves security, reduces EMI susceptibility, and enables robust remote monitoring.
The product is covered under Eaton's policy: one year from installation or eighteen months from the date of shipment, whichever occurs first. For regional variations or extended coverage, contact Eaton directly to confirm the applicable warranty terms.
Common applications include transformer protection in substations, OEM power equipment, and industrial facilities requiring integrated protection, metering, and remote diagnostics.
