Eaton ETR-5000-2A2LA1 Transformer relay - 19-300/40-250V

The 8 digital inputs and 9 outputs provide versatile I/O for protection logic and remote signaling, reducing wiring complexity and enabling quicker fault isolation, which translates to lower downtime and safer equipment operation. In practice, the business impact is clearer protection coordination and faster diagnostic feedback, especially in substations or OEM equipment where space is at a premium and wiring runs are lengthy. The ability to communicate over Mbus TCP or DNP3 TCP/UDP via LC duplex fiber Ethernet directly supports SCADA integration, lowering total cost of ownership by simplifying remote monitoring, improving maintenance planning, and reducing on-site visits. The 2 current sensing inputs, along with configurable phase current options of 5A and 1A, enable precise metering and protection relays aligned with transformer loads and power quality needs. Power supply flexibility—19-300Vdc and 40-250Vac at 50/60 Hz—ensures compatibility across diverse site conditions, while removable terminals and projection mounting streamline installation and field service. I/O options such as IRIG-B, Trip Coil Monitor, URTD Interface, and Sensitive Ground Input extend protection coverage for critical assets. While compliance data requires direct confirmation from Eaton, the system’s modular inputs and robust fiber communications support scalable protection architectures, reducing future upgrade costs and enabling phased asset modernization. These features collectively support reliable transformer protection and diagnostic insights in complex multi-feed environments.
