Quick Summary

Eaton transformer relay protects transformer networks in medium- to high-voltage assets for reliable power distribution across industrial sites. Engineers often struggle with timely fault detection, nuisance trips, and downtime that disrupt production and extend maintenance windows. Compliance details are provided by the manufacturer, and the unit features a conformal coating option for harsh environments. With Mbus TCP or DNP3 TCP/UDP over LC duplex fiber Ethernet and 8 inputs/9 outputs, it enables scalable, secure remote monitoring and rapid fault isolation. This capability supports transformer protection and rugged operation, delivering improved asset uptime and informed maintenance planning. The result is safer, more predictable power delivery and lower total cost of ownership for critical electrical infrastructure.

FAQs

Install using the removable terminals and semi-flush mounting to minimize panel depth. Verify the 19-300 Vdc / 40-250 Vac power range and 50/60 Hz supply, then connect the 8 digital inputs, 9 outputs, and 2 analog channels per the transformer protection scheme. Ensure proper fiber Ethernet connections for Mbus TCP or DNP3 TCP/UDP communication.
Key specs include 8 digital inputs, 9 digital outputs, 2 analog inputs, 2 analog outputs, power range 19-300 Vdc / 40-250 Vac, 50/60 Hz, Mbus TCP or DNP3 TCP/UDP over LC duplex fiber Ethernet, IRIG-B Trip Coil Monitor, conformal coating, removable terminals, and base relay compatibility with ETR-4000.
Compliance details are provided by the manufacturer. The product supports rugged operation with conformal coating and flexible communications, and detailed compliance documentation can be requested from Eaton for CE, IP, and SIL considerations as applicable to your installation.
Remote monitoring via Mbus TCP or DNP3 TCP/UDP over fiber reduces field visits, while the 8/9 IO configuration and Trip Coil Monitor enable faster fault isolation and verification. This leads to shorter MTTR, fewer unnecessary trips, and lower ongoing maintenance costs across transformer assets.
This relay is ideal for transformer protection, metering, and monitoring in industrial power systems, OEM equipment, and control rooms. It supports scalable protection schemes, precise timing via IRIG-B, and rugged installation with conformal coating for harsh environments.
