Eaton ETR-5000-2A2LB1 Transformer Relay - Mbus/DNP3 Enet

Eight digital inputs and nine outputs provide on-board protection logic, reducing external wiring and cutting trip decision time. This consolidation improves fault isolation and system stability, essential in high-energy transformer protection schemes. In new builds or retrofit projects, the compact I/O set simplifies panel design and minimizes enclosure space, delivering a faster path to compliant protection and metering. Communication is provided via Mbus TCP or DNP3 TCP/UDP over LC duplex fiber optic Ethernet, delivering robust, low-latency data exchange. This enables secure remote monitoring, event logging, and seamless SCADA integration, reducing on-site visits and accelerating fault analysis. For greenfield or brownfield projects, the long-haul fiber option supports distributed assets without compromising performance. Wide power-supply range supports diverse plant electrification: 19–300 Vdc or 40–250 Vac, with a 50/60 Hz frequency rating. That means fewer card changes when migrating between industrial networks or upgrading equipment, lowering commissioning risk. The flexible supply also simplifies spare-part inventories and procurement, improving uptime during transitions. Conformal coating protects circuitry in challenging environments, extending service life in outdoor, damp, or dusty installations. The I/O options—URTD interface, Sensitive Ground Input, Trip Coil Monitor, IRIG-B—provide expanded protection logic and precise trip coordination for complex protection schemes. Designed as an evolution of the ETR-4000 base relay, the unit preserves familiar protection logic while expanding inputs, outputs, and diagnostics. Removable terminals and a projection mounting method simplify installation, testing, and field maintenance, enabling faster turnarounds during maintenance windows.
