Quick Summary

Eaton transformer relay protects transformers and circuits in industrial power systems. Engineers often struggle with coordinating protection logic, communications, and diagnostics across dispersed assets, leading to slower fault isolation. Typical certifications for this class include CE compliance, IP ratings, and SIL considerations; verify exact markings on Eaton’s official datasheets. By deploying this device, teams gain reliable transformer protection, flexible Modbus RTU or DNP3 RTU communications over RS-485, and scalable metering integration for plant-wide visibility. The result is faster fault isolation, improved SCADA integration, and reduced downtime costs, all while supporting future digital upgrades and cross-site standardization.

FAQs

Consider panel space for the semi-flush mounting and the removable terminals to simplify wiring during retrofit. Plan for a 19-300 Vdc or 40-250 Vac power supply and 50/60 Hz operation. Ensure RS-485 network availability for Modbus RTU or DNP3 RTU communications and verify grounding and interlock configurations before commissioning.
It combines 8 digital inputs with 9 outputs, flexible Modbus RTU/DNP3 RTU over RS-485, and IRIG-B/Sensitive Ground Input options, enabling precise protection schemes, fast fault isolation, and robust monitoring. This makes it well-suited for complex transformer protection in manufacturing, data centers, and energy-intensive facilities.
Yes. The relay communicates over RS-485 via Modbus RTU or DNP3 RTU, allowing seamless integration with existing SCADA and DCS platforms. This standard interface supports remote monitoring, event logging, and coordinated protection actions across multi-device networks.
Compliance details are provided by the manufacturer; check Eaton’s official datasheets and the E-Series protective relays documents for CE, IP, SIL, and related certifications where applicable. Always verify the exact markings on the latest Eaton specification sheets before procurement and installation.
The device carries Eaton’s warranty policy of one year from installation or eighteen months from shipment, whichever occurs first. This warranty, combined with improved fault isolation, reduced downtime, and SCADA-ready integration, contributes to lower operational risk and faster return on investment in transformer protection deployments.
