Eaton ETR-4000-2A2LA0 Transformer Relay - Mbus TCP/DNP3

Feature → Business Impact → Application: Flexible I/O architecture with 8 digital inputs and 9 digital outputs, plus 2 current sensing inputs, enables complex protection schemes and accurate fault detection. This reduces misoperation and downtime while improving protection coordination for transformer banks and motor drives. Application: transformer protection relays in substations and process plants. Feature → Business Impact → Application: Dual network communication via Mbus TCP or DNP3 TCP/UDP over LC duplex fiber Ethernet provides secure, scalable remote monitoring and diagnostics. This supports energy management integration and SCADA interoperability, lowering on-site maintenance visits. Application: plant-wide protection telemetry and condition monitoring. Feature → Business Impact → Application: Wide power supply range 19-300Vdc and 40-250Vac with 50/60 Hz compatibility ensures plug-and-play installation across varying plant voltages, reducing engineering time and inventory. Application: retrofits and new builds in mixed-voltage environments. Feature → Business Impact → Application: I/O options including Sensitive Ground Input, IRIG-B time sync, and Trip Coil Monitor improve trip reliability and fault timing accuracy, enabling precise protection decisions. Application: critical transformer protection in power distribution networks. Feature → Business Impact → Application: Removable terminals and semi-flush mounting simplify installation and future maintenance, decreasing commissioning time and service costs. Application: panel installations in space-constrained electrical rooms.
