Modular IO and robust communications enable precise protection logic and flexible plant integration, reducing downtime and enabling rapid fault localization. With 8 digital inputs, 9 outputs, 2 analog inputs, and 2 analog outputs, the device supports comprehensive protection schemes and metering applications for transformers up to 50/60 Hz. The dual power options—19-300 VDC and 40-250 VAC—allow seamless integration into varying plant electrical infrastructures, while removable terminals and semi-flush mounting simplify field installation and maintenance. IRIG-B, Trip Coil Monitor, Sensitive Ground Input, and URTD Interface options provide extended diagnostics and fault isolation, minimizing service interruptions in critical power systems. The built-in Modbus RTU or DNP3 RTU over RS-485 ensures easy integration with SCADA, energy meters, and protection relays, reducing commissioning time and integration risk. Compatibility with the ETR-4000 base delivers a proven protection platform with scalable upgrade paths for future protection needs.

FAQs

Begin by evaluating the transformer protection topology and confirm compatibility with the ETR-4000 base. Use the removable terminals for quick field wiring, then connect RS-485 Modbus RTU or DNP3 RTU to your SCADA or PMU system. Ensure the 19-300 Vdc or 40-250 Vac power supply is within spec and verify the semi-flush mounting for secure cabinet deployment. Finally, configure digital and analog IO (8/2) to match your protection, metering, and monitoring requirements, enabling coordinated trips and accurate fault reporting.
Key specs include a dual power range of 19-300 Vdc and 40-250 Vac, 50/60 Hz operation, 8 digital inputs, 9 outputs, 2 analog inputs, and 2 analog outputs. Communications are via Modbus RTU or DNP3 RTU over RS-485, with optional interfaces like IRIG-B, URTD, and Sensitive Ground Input. The device supports transformer protection functions, metering, and zone-selective interlocking in a compact relay package.
Yes. The ETR-5000-2B2GA0 is designed for transformer protection and metering in industrial power systems. Its 8/9 IO, Modbus/DNP3 communications, and flexible power options simplify integration into switchgear and motor control centers. The device supports protection coordination, remote monitoring, and diagnostic capabilities that help minimize unplanned outages while providing scalable protection for evolving plant architectures.
Compliances for this family are provided by the manufacturer. Industry-standard certifications such as CE and IP ratings are commonly pursued for transformer protection relays to ensure safety and environmental suitability; however, confirm specific certifications with Eaton for the exact lot and installation. This approach helps ensure regulatory alignment in your region and facility class.
The device ships with a one-year warranty from installation or an eighteen-month window from shipment, whichever occurs first, per Eaton policy. Its modular IO and removable terminals reduce commissioning and maintenance time. Remote monitoring via Modbus/DNP3 enables proactive fault detection, lowering downtime costs and extending transformer life. The compatibility with the ETR-4000 base supports future upgrades without replacing the entire protection platform.
