Quick Summary

The Eaton transformer relay is a protection and monitoring device for transformer protection in industrial power systems. In practice, engineers often struggle with timely fault detection, miscoordination of protection schemes, and unreliable remote visibility in harsh environments. This model combines transformer-specific protections with flexible I/O, Ethernet and RS-485 communications, and time-synchronization options to support fast, coordinated responses. Certifications vary by region and configuration; confirm CE, IEC and IP-related approvals with Eaton to ensure compliance in your facility. Along with robust protection, the device enables remote monitoring, metering integration, and easy retrofit into existing protection architectures, delivering measurable business value.

Flexible I/O and communications enable complex protection logic with minimal wiring. The unit offers 8 digital inputs, 9 outputs, plus 2 analog I/O and 2 current sensing inputs, all powered from 19-300 Vdc or 40-250 Vac with 50/60 Hz. RS-485 Modbus RTU and Ethernet TCP permit plant-wide monitoring and remote data access, reducing site visits and speeding diagnostics. Transformer protection functions deliver faster fault isolation, better protection coordination, and enhanced system reliability, with differential protection, voltage/current protection, and zone selective interlocking. Installation is streamlined by removable terminals and projection mounting, while conformal-coated circuit boards improve durability in harsh environments. I/O options like Trip Coil Monitor, Sensitive Ground Input, URTD Interface, and IRIG-B timing support advanced protection schemes and precise time synchronization. Compatibility with the ETR-4000 base relay simplifies retrofits and minimizes project risk, backed by Eaton’s warranty and support for long-term uptime.
