Eaton ETR-5000-2A3EA1 Transformer Relay - Profibus-DP RS485

Feature → Business Impact → Application: 8 digital inputs and 9 digital outputs enable comprehensive protection logic and remote signaling, reducing controller complexity and enabling faster fault isolation in substations and on-the-fly diagnostics for plant-wide protection schemes. This translates to improved system uptime and easier integration with PLCs over Profibus-DP over RS-485 for rugged industrial networks. Feature → Business Impact → Application: 2 current sensing inputs plus 1 voltage sensing input support multi-parameter protection (current, voltage, differential) and metering, delivering accurate fault detection and energy monitoring for transformer banks in OEM equipment and centralized substations. Feature → Business Impact → Application: Power supply range of 19-300 VDC and 40-250 VAC with 50/60 Hz, plus removable terminals and projection mounting, simplify field installation, reduce commissioning time, and enable flexible panel layouts in new builds or retrofits. Feature → Business Impact → Application: I/O options including Sensitive Ground Input, Trip Coil Monitor, URTD Interface, and IRIG-B provide extended interoperability with protective schemes, trip coordination, and time synchronization—minimizing misoperations in high-stakes protection tasks. Feature → Business Impact → Application: Base relay compatibility with ETR-4000, Zone Selective Interlocking (2 zones), and 8/9 I/O count supports scalable protection architecture, lowering total cost of ownership by reusing a common platform across multiple transformer configurations. Feature → Business Impact → Application: Profibus-DP over D-Sub/RS-485 communications ensures robust, standards-based integration with enterprise and automation networks, enabling centralized diagnostics, event logging, and unified maintenance procedures across plants.
