Eaton Specification Sheet - ETR-5000-2B2GB1
Modbus RTU or DNP3 RTU over RS-485 support provides flexible, vendor-agnostic communication. This enables centralized monitoring, alarms, and fast fault isolation in SCADA systems, reducing downtime and improving asset visibility across the facility. The eight digital inputs and nine outputs, plus two analog inputs and two analog outputs, support versatile protection schemes and metering, enabling precise interlock logic and richer plant data for optimization. Power supply range of 19-300 Vdc and 40-250 Vac with 50/60 Hz compatibility ensures compatibility with varied plant electrical rails, while removable terminals and projection mounting simplify installation and maintenance, reducing commissioning time and improving field reliability. Conformal-coated circuit boards enhance resilience in harsh environments, helping uptime in outdoor or industrial settings. The protective functions cover voltage, current, power, and differential protection, meeting common transformer protection requirements and supporting scalable relays in expanding plants. I/O options like URTD interface, IRIG-B, Trip Coil Monitor, and Sensitive Ground Input broaden integration with protection schemes and monitoring networks, easing retrofits and upgrades.
