Eaton ETR-4000 Transformer Relay - Profibus-DP

Feature → Business Impact → Application: 8 digital inputs and 9 digital outputs enable comprehensive input/output management, reducing wiring complexity and enabling centralized protection logic for transformer protection relays used in centralized industrial control. This translates to faster commissioning, easier maintenance, and improved diagnostic visibility in OEM panels. Feature → Business Impact → Application: Profibus-DP over D-Sub / RS-485 provides reliable, industry-standard communication, enabling seamless integration with existing PLCs and SCADA systems, improving data integrity and reducing integration risk in transformer protection schemes for power distribution. Feature → Business Impact → Application: Dual power-supply range of 19-300 Vdc and 40-250 Vac supports both DC and AC powered control circuits, increasing installation flexibility and minimizing the need for additional power conditioning in transformer protection relays for manufacturing lines. Feature → Business Impact → Application: Conformal coating and removable terminals enhance reliability in harsh environments, enabling coating protection against moisture and dust and simplifying field maintenance for retrofit projects in substations and machine rooms. Feature → Business Impact → Application: I/O options including Trip Coil Monitor, IRIG-B, Sensitive Ground Input, and URTD Interface expand diagnostic and monitoring capabilities, delivering improved fault localization and reduced downtime in transformer protection applications. Feature → Business Impact → Application: Zone selective interlocking and differential/current protection metering provide precise protection coordination, enabling safer operation and faster isolation in high-energy transformer installations across OEM and panel-building projects.
