Quick Summary

The Eaton transformer relay protects transformer circuits in industrial power systems, delivering precise protection and metering. Operators often wrestle with complex protection schemes and challenging integration with control networks, which can drive downtime and maintenance costs. Compliance considerations vary by region, so verify CE, SIL, and IP-related details with Eaton to ensure site readiness. This device combines robust transformer protection with Profibus-DP over D-Sub/RS-485 communication, and it supports a wide power-supply range and scalable I/O for flexible protection schemes. With backwards compatibility to the ETR-4000 and conformal coating, it reduces wiring, speeds commissioning, and delivers reliable monitoring for substations, switchgear, and automation panels.

FAQs

Plan a retrofit by verifying base compatibility to ensure seamless module replacement. Use removable terminals and semi-flush mounting for quick service access. Wire eight digital inputs, nine outputs, two analog inputs, and two analog outputs as specified, and follow the manufacturer’s guidance for correct Profibus-DP integration with RS-485 connections.
The device delivers differential protection, current protection and metering, voltage protection and metering, and power protection and metering. These functions support comprehensive transformer protection in industrial switchgear and substations, with integrated monitoring to simplify maintenance and improve reliability.
Yes. It uses Profibus-DP over D-Sub/RS-485 for PLC communication, enabling straightforward integration into existing control architectures. This reduces commissioning time and supports centralized protection, metering, and monitoring across plant networks.
Compliance details vary by region; consult Eaton for CE, SIL, IP ratings, and related certifications. The relay features conformal coated circuit boards, which provide enhanced environmental resilience in harsh industrial settings, but specific regulatory approvals should be confirmed for your site.
Backwards compatibility with the ETR-4000 reduces replacement costs, while the conformal coating and modular I/O simplify maintenance in harsh environments. Wider power range and RS-485 communication improve uptime, reduce wiring errors, and accelerate commissioning, delivering measurable savings in downtime and lifecycle costs.
