Eaton Transformer Relay ETR-4000-2A1LB0 - Mbus TCP/DNP3 over LC fiber

Feature → Business Impact → Application: 8 digital inputs and 9 digital outputs enable comprehensive protection logic, signaling, and remote control within a single device, reducing panel complexity and wiring time. This simplifies commissioning and lowers startup costs while speeding up fault localization in transformer networks. Application: transformer protection and process automation in substations or industrial facilities. Feature → Business Impact → Application: Two current sensing inputs provide accurate differential protection and metering data, supporting energy management programs and precise fault detection without additional sensors. Application: generator/transformer protection schemes requiring real-time current-based decisions. Feature → Business Impact → Application: Power supply options of 19-300 Vdc and 40-250 Vac offer installation flexibility across varying plant voltages, enabling easier retrofits and upgrades without separate power supplies. Application: new builds and modernization projects with mixed voltage environments. Feature → Business Impact → Application: Mbus TCP or DNP3 TCP/UDP over LC duplex fiber Ethernet ensures scalable, secure communication to SCADA systems, enabling remote monitoring and fast alarm escalation. Application: integration in digital ecosystems and remote diagnostics. Feature → Business Impact → Application: I/O options including Trip Coil Monitor, IRIG-B timing, URTD interface, and Zone Selective Interlocking (2 zones) boost protection reliability and synchronization, reducing fault impact and improving system coordination. Application: high-reliability transformer protection in critical infrastructure. Feature → Business Impact → Application: Conformal coating and removable terminals simplify maintenance in harsh environments and extend field service life, minimizing downtime during upgrades or repair. Application: durable deployment in industrial cabinets and outdoor-rated enclosures.
