Eaton ETR-4000-2A2GB0 Transformer Relay - Modbus RTU/RS-485

Feature → Business Impact → Application: 8 digital inputs and 9 digital outputs streamline wiring and integration, reducing installation time and panel footprint while enabling richer protection logic for transformer assets in substations and industrial plants. The result is faster commissioning and lower lifecycle costs in busy maintenance windows. Feature → Business Impact → Application: Modbus RTU or DNP3 RTU over RS-485 with D-Sub connectivity enables seamless SCADA/EMS integration, improving real-time visibility and predictive maintenance across distributed transformer fleets. This supports tighter fault localization and reduced unplanned downtime in critical energy infrastructure. Feature → Business Impact → Application: Dual power-supply range (19-300 Vdc, 40-250 Vac) and 50/60 Hz operation provide flexible deployment in variable electrical environments, lowering the need for dedicated power conditioning and simplifying spare-parts planning for OEMs. Feature → Business Impact → Application: I/O options including Sensitive Ground Input, Trip Coil Monitor, IRIG-B URTD interface enhance protection accuracy and time synchronization, delivering precise protection coordination in complex protection schemes for utilities and industrial users. Feature → Business Impact → Application: Conformal-coated circuit boards and removable terminals improve reliability in harsh environments and ease maintenance, supporting longer asset life and faster field service in harsh industrial settings. Feature → Business Impact → Application: Zone selective interlocking and robust metering capabilities support advanced protection strategies, enabling selective tripping and improved coordination in transformer banks for substations and large OEM installations.
