الوصف
The GE DS200UCIAG1A is a UC2000 Motherboard that serves as a central component within the R Core (or “R” module) of a GE Mark V Speedtronic Turbine Control System.1
Essentially, it’s the primary mounting and interface board that brings together the core processing power and communication modules for a single redundant control path.2
⚙️ Key Function and Role
The DS200UCIAG1A is not a processor itself, but rather the structural and electrical backbone for the main computer boards within the control system’s R Core.3
- Motherboard/Backplane: Its main function is to provide the connectors and electrical pathways necessary to mount and interconnect the other critical processing and communication boards.4
- Hosting Critical Modules: It provides dedicated mounting locations for essential daughterboards, which can include:
- The UCPB (UC2000 Processor Board) or similar CPU card, which performs the main control sequence.5
- The PANA (ARCNET no-LAN driver board) or other network interface boards.6
- Up to two GENI (GE Network Interface) Boards.
- Signal Translation: The board includes an onboard microprocessor (such as a 196 processor) to perform preliminary data processing.7 For instance, it may translate fuel skid pressure signals received from the TCSA board before sending them to the UCPB for use in the main control sequence software.8
- System Core: In the Mark V system, the R Core (R1, R2, or R3) is one of the redundant control lanes. The DS200UCIAG1A is the heart of this core, ensuring all local components communicate correctly.
