Quick Summary

Eaton transformer relay protects transformers by monitoring fault conditions and coordinating protective actions in power systems. Engineers often struggle to stitch together protection logic, metering, and secure communications within a single device. The ETR-5000-2B1IA0 combines differential, power, voltage, and current protection with metering and both RS-485 Modbus RTU and Ethernet TCP/IP connectivity, simplifying integration. The published data does not specify CE, SIL, or IP certifications; confirm exact compliance with Eaton and reference the datasheet before deployment. The device’s 8 digital inputs, 9 outputs, 2 analog inputs, and 2 analog outputs support comprehensive protection schemes, enabling faster deployment, reduced wiring, and improved uptime for transformer installations in industrial and utility environments.

FAQs

The ETR-5000-2B1IA0 supports 8 digital inputs, 9 outputs, 2 analog inputs, and 2 analog outputs, with removable terminals and semi-flush mounting. It tolerates a power range of 19-300 Vdc and 40-250 Vac, 50/60 Hz, enabling direct integration into many standard transformer control panels without extensive re-wiring. Verify panel space and terminal layout during site surveys.
Key performance features include differential protection, power protection with metering, voltage protection with metering, and current protection with metering. The device also offers zone selective interlocking and a base relay (ETR-4000). Combined with RS-485 Modbus RTU and Ethernet Modbus TCP, these specs support fast fault isolation, accurate energy measurement, and reliable remote monitoring in industrial and utility environments.
Yes. The ETR-5000-2B1IA0 supports Modbus RTU over RS-485 for field devices and Modbus TCP over Ethernet RJ-45 for networked control systems. This dual connectivity enables local device integration and remote SCADA or DMS monitoring, reducing wiring complexity and enabling centralized protection strategies across distributed transformer assets.
The provided data lists Compliances as Contact Manufacturer, with no explicit CE, SIL, or IP ratings. Before field deployment, contact Eaton for the exact certifications and confirm regulatory compliance for your region. Review the accompanying datasheet and datasheet links to ensure alignment with local electrical codes and protection standards.
ROI comes from reduced panel wiring, fewer external relays, and streamlined commissioning. The ETR-5000-2B1IA0 combines protection, metering, and communications in a single device, lowering installation labor and maintenance costs. A one-year warranty (or 18 months from shipment per Eaton policy) further mitigates risk and supports predictable maintenance planning.
