Eaton Specification Sheet - ETR-5000-2B0BA1
Modbus RTU or DNP3 RTU over RS485 enables seamless SCADA integration and remote fault notification, reducing downtime and accelerating response times. This translates into improved asset availability and safer transformer operation in substations and manufacturing plants. The relay provides 8 digital inputs, 9 digital outputs, and 2 analog inputs plus 2 analog outputs, enabling complex protection schemes, metering, and signaling without adding external devices. The result is a compact protection hub that minimizes panel space and cabling costs while delivering precise control and fast trip coordination. With a universal power supply range (19-300 Vdc, 40-250 Vac) and 50/60 Hz operation, the unit fits diverse plant electrical environments, simplifying retrofits and new builds alike. Projection mounting and removable terminals streamline installation and maintenance, reducing commissioning time and risk of wiring errors. The device supports advanced protection functions (power, voltage, differential protection) and optional interfaces (Trip Coil Monitor, IRIG-B, URTD), enabling zones like Zone Selective Interlocking to improve selectivity and fault isolation. Warranty terms and an established Eaton ecosystem further lower total cost of ownership by simplifying service, spare parts, and firmware updates.
