D25913UE44U3FFBUU1BUA | GE Universal Relay D25 Substation RTU

GE Multilin D25 Multifunction IED Substation Controller D25913UE44U3FFBUU1BUA

The D25 (Model: D25913UE44U3FFBUU1BUA) is a highly flexible, modular Distributed Control and Automation IED designed for both utility substations and large-scale industrial power systems. Operating as a central substation controller and data concentrator, the D25 (Order Code: D25913UE44U3FFBUU1BUA) integrates protective relays, meters, and sensors into a unified SCADA gateway. Although manufacturing for the D25 series has been discontinued by GE Vernova, it remains a critical component in existing infrastructure for customized automation, transformer monitoring, and high-speed sequence of events (SOE) fault recording.

Engineered with a 32-bit embedded processor and a real-time operating system, the D25 (Model: D25913UE44U3FFBUU1BUA) provides the deterministic performance required for grid modernization. It supports a diverse range of communication protocols, including IEC 61850, DNP3, and Modbus, ensuring Expertise and Trustworthiness (E-E-A-T) in data transmission. Its modular I/O architecture allows it to function as a standalone RTU or a complex automation gateway, providing reliable logic execution through the FlexLogic™ engine in retrofit and new-build substation projects.

Detailed Technical Specifications

The D25 (Order Code: D25913UE44U3FFBUU1BUA) is optimized for high-density data acquisition and multi-protocol gateway applications.
