Eaton Specification Sheet - ETR-5000-2B1EA1
8 digital inputs and 9 digital outputs plus 2 analog inputs and 2 analog outputs provide a single, integrated protection, metering, and control interface. This dense I/O enables precise fault detection, reduces nuisance trips, and enables coordinated protection across transformer assets. Application: suited for transformer protection in OEM equipment, substations, and process plants requiring multi-domain protection and metering. Power supply range of 19-300 Vdc and 40-250 Vac with 50/60 Hz operation allows flexible installation in diverse environments, reducing the need for extra conditioning and lowering installation costs. Benefit: easier retrofits and scalable protection schemes; Application: new builds and expansions with minimal downtime. Profibus-DP over D-Sub/RS-485 enables seamless PLC/SCADA integration, accelerating commissioning and improving remote diagnostics. Application: OEM equipment and distributed control architectures. I/O options including IRIG-B, URTD Interface, Sensitive Ground Input, and Trip Coil Monitor support time synchronization and advanced fault isolation, enhancing protection accuracy across complex systems. Warranty and service considerations are included to support long-term ownership, maintenance planning, and total cost of ownership improvements.
