Eaton ETR-4000-2A2GB1 Transformer Relay - Modbus RTU

Feature → Business Impact → Application: The ETR-4000 offers 8 digital inputs and 9 outputs, enabling complex protection schemes with minimal wiring, reducing installation time and potential fault points. This translates to faster fault isolation and improved uptime in substations or industrial plants where transformer reliability is critical. Application: Large-scale power distribution and transformer protection projects that require robust I/O after installation. The Modbus RTU or DNP3 RTU over RS-485 interface provides seamless integration with SCADA and energy management systems, delivering real-time monitoring and remote diagnostics that cut maintenance costs and improve decision speed. Application: OEMs integrating protective relays into packaged equipment or retrofit projects. With a broad power supply range (19-300 Vdc, 40-250 Vac) and 50/60 Hz compatibility, the unit fits diverse plant electrical infrastructures, reducing the need for additional power conditioning equipment. Application: Industrial facilities with mixed DC/AC supplies. Conformal coating on PCBs and removable terminals improve field reliability and serviceability, lowering lifecycle costs. Application: Harsh environments with vibration, humidity, or chemical exposure. I/O options include IRIG-B, Sensitive Ground Input, Trip Coil Monitor, URTD Interface, enabling precise timing and enhanced interlocking schemes. Application: New build or retrofits requiring synchronized protection and advanced trip logic. Project teams benefit from projection mounting and a compact footprint, which simplifies panel design, panel space planning, and future scalability. Application: Control cabinets with limited space and future-proof expansion needs.
