Eaton ETR-5000-2A1GA1 Transformer Relay - Modbus RTU / DNP3 RTU

Eight digital inputs and nine outputs give you expansive monitoring and signaling capability, while two current sensing inputs enable precise fault detection and metering. This translates to faster protection decisions and reduced risk of transformer damage, supporting operations across manufacturing, utilities, and data centers. The wide power-supply range of 19-300 VDC and 40-250 VAC at 50/60 Hz ensures easy integration with existing plant power rails, minimizing wiring redundancy and simplifying retrofit projects. Modbus RTU or DNP3 RTU over RS-485 provides interoperable communication with SCADA and MES systems, improving visibility and control without extra gateway hardware. Removable terminals and projection mounting simplify installation, maintenance, and field upgrades, reducing total cost of ownership. I/O options such as URTD Interface, IRIG-B Trip Coil Monitor, and Sensitive Ground Input enable advanced protection schemes and precise timing for critical feeders. Zone selective interlocking (2) supports coordinated protection, improving selectivity and minimizing outage scope in substations and multi-bus configurations. This combination delivers measurable efficiency gains, compliance assurance, and a clear path to scalability as your protection strategy evolves.
