Eaton ETR-5000-2A1EB1 Transformer Relay - Profibus-DP

8 digital inputs and 9 digital outputs enable integrated protection logic and local control for transformer circuits, reducing external IO hardware. This consolidation lowers wiring complexity, shortens installation time, and improves reliability by minimizing connection points. It’s well-suited for transformer protection in OEM panels and distribution cabinets, where space, accessibility, and fault tracing are critical. Broad power supply compatibility supports 19-300 Vdc or 40-250 Vac input, enabling seamless integration with existing plant power architectures. The wide range simplifies procurement and reduces the need for additional power conditioning equipment, cutting total cost of ownership. Typical applications include feeder protection and transformer protection in mixed-voltage environments. Profibus-DP over D-Sub/RS-485 provides ready network integration with existing PLCs and SCADA systems for remote monitoring, diagnostics, and coordinated protection actions across multiple devices, boosting uptime and situational awareness. Protection versatility is expanded with I/O options such as URTD Interface, Trip Coil Monitoring, and IRIG-B input, enabling tailored protection schemes for complex transformer configurations. The combination of 8 inputs, 9 outputs, and Zone Selective Interlocking supports fast, safe fault isolation, lower downtime, and straightforward upgrades to future protection architectures.
