DS215UCIAG1AZZ05A is a UC2000 Core Motherboard manufactured and designed by General Electric as part of the Mark V Series used in GE Speedtronic Gas Turbine Control Systems. It features one microprocessor and several PROM modules. It also has one jumper and one connector for attaching other boards. A modular-type connector allows for the connection of a daughter card to the board. The daughter card is physically attached to the board via standoffs on the board, and the modular connector offers power and signal connections. Because the use of a daughter card requires more space in the board cabinet, it is standard practice to replace it in the same location when replacing it. The board's 10 LEDs provide a health status and signal if an error occurs.
