Eaton Specification Sheet - ETR-5000-2A0CA1
Eight digital inputs and nine digital outputs provide versatile protection logic with straightforward wiring. The arrangement supports complex protection schemes and streamlined field wiring for transformer protection applications in OEMs and industrial plants. Two current sensing inputs enable differential and current-based protection alongside metering capabilities. The capability to monitor both 5A and 1A current levels supports accurate protection and scalable metering across transformer sizes. Power supply is selectable across 19-300 Vdc and 40-250 Vac, with a 50/60 Hz frequency rating. This broad range simplifies installation across varying plant voltages and minimizes inventory. Modbus TCP or DNP3 TCP/UDP communications over Ethernet RJ45 provide seamless integration with SCADA, middleware, and control systems. This reduces commissioning time and improves data visibility for transformer protection and diagnostics. Projection mounting and removable terminals streamline installation, servicing, and field upgrades. The modular design supports fast panel integration and straightforward maintenance in high-demand electrical rooms. I/O options include URTD Interface IRIG-B Trip Coil Monitor and Zone Selective Interlocking (2), enabling synchronized protection across feeders and equipment. With eight inputs and nine outputs, the relay supports scalable protection architectures and future expansion.
