Eaton ETR-5000-2B3FA0 Transformer Relay - Modbus RTU or DNP3 RTU over Fiber

Feature: Modular protection with a base ETR-4000 and removable terminals. Benefit: Faster field wiring changes and easier maintenance, cutting commissioning time and labor costs on retrofit projects. Application: Transformer protection panels in substations and plant power rooms. The pattern continues with a comprehensive I/O set: 8 digital inputs, 9 digital outputs, 2 analog inputs, and 2 analog outputs. Business impact: consolidated protection and metering signals in a single device, reducing external I/O wiring and potential failure points. Application: Real-time protection, alarming, and metering in transformer banks. Feature: Wide power compatibility—19-300 Vdc and 40-250 Vac, 50/60 Hz. Benefit: Simplified inventory and compatibility with mixed DC/AC feeders, lowering spare parts costs. Application: Mixed-power installations in renewables and industrial facilities. Feature: Fiber-based Modbus RTU or DNP3 RTU communications. Benefit: EMI immunity and reliable SCADA integration, enabling remote diagnostics and faster fault isolation. Application: Industrial control rooms and remote substations. Feature: Trip Coil Monitor and Sensitive Ground Input. Benefit: Enhanced fault detection and safer shutdown signaling, reducing downtime risk. Application: Critical transformer protection schemes. Feature: Zone Selective Interlocking (2). Benefit: Coordinated breaker operation and selective tripping, improving system reliability. Application: Substation protection coordination and feeder management. Installation notes: Removable terminals and semi-flush mounting simplify installation and future upgrades, supporting faster commissioning and easier field service.
