FAQs

Plan for semi-flush mounting and removable terminals to ease field wiring. The unit is compatible with the base ETR-4000 and supports URTD interface and IRIG-B options for retrofits. Ensure RS-485 communication is properly terminated and that the 19-300 Vdc / 40-250 Vac power rails are correctly wired for your 50/60 Hz network. This reduces commissioning time and prevents wiring errors.
Verify eight digital inputs, nine outputs, two analog inputs, and two analog outputs to match protection schemes. Confirm the power supply range (19-300 Vdc, 40-250 Vac) and the 50/60 Hz frequency rating. Confirm Modbus RTU or DNP3 RTU over RS485 communication to ensure compatibility with your SCADA and protection systems.
Yes. It is designed for transformer protection with distributed diagnostics and remote monitoring via RS485 interfaces. Its flexible I/O and multi-protocol support enable integration with SCADA and protection schemes across data centers, OEM equipment, and utility substations, improving protection coordination and reducing downtime.
Compliance details vary by region; contact the manufacturer for CE, SIL, and IP ratings where applicable. The warranty policy is Eaton Selling Policy 25-000, offering one year from installation or eighteen months from shipment, whichever occurs first, providing a clear framework for asset protection and service planning.
Refer to the Eaton specification sheet for ETR-5000-2B3BA0 and the available brochures for system integration guidance.
