Flexible power range and voltage compatibility drive global deployment and simplified stocking, enabling quicker installation in sites with 19-300Vdc or 40-250Vac supply. The business impact is reduced wiring complexity and fewer power-stage substitutions, which translates to lower project risk and faster time-to-operation in transformer protection applications. The 8 digital inputs and 9 digital outputs, paired with 2 current-sensing inputs, provide rich monitoring and control capabilities, improving SCADA integration and enabling precise fault localization in power networks. Modbus TCP or DNP3 TCP/UDP over Ethernet RJ45 ensures seamless communication with existing control systems, leading to enhanced visibility, faster decision-making, and improved maintenance planning. I/O options like IRIG-B, Trip Coil Monitor, and Sensitive Ground Input support high-reliability protection schemes in mission-critical environments. The base-relay compatibility with ETR-4000 simplifies upgrades and minimizes engineering change, while semi-flush mounting and removable terminals facilitate cabinet wiring and field service. Zone selective interlocking (2) reduces breaker opening times, cutting downtime and improving system stability. This combination yields predictable protection, regulatory alignment, and reduced total cost of ownership in transformer protection implementations.
