GE DS200UCIAG1ACB UC2000 Motherboard

الوصف

The GE DS200UCIAG1ACB is a UC2000 Motherboard (or R Core Motherboard) used in the GE Mark V Speedtronic Turbine Control System.¹

This board is the central wiring and connection point for the main processing and communication boards within one of the redundant control cores (the ‘R’ core) of the turbine control system.²

💡 Key Function and Role

The primary purpose of the DS200UCIAG1ACB is to function as a backplane or chassis for other vital modules, integrating them to form the functional computing unit of a single control lane.

• Central Interface: It provides the necessary connectors to mount and interface the core components that execute the turbine control logic.³
• Module Hosting: It hosts several critical daughterboards, including:
  • The UCPB (UC2000 Processor Board) or a similar central processing unit (CPU).⁴
  • The PANA (ARCNET No-LAN Driver Board) for network communication.⁵
  • Up to two GENI (GE Network Interface) Boards for I/O and communication with field devices.⁶
• Signal Pre-processing: The board itself contains a smaller onboard microprocessor (e.g., a 196 processor) that is responsible for essential, localized signal translation.⁷ For example, it translates fuel skid pressure signals received from the TCSA board before writing them to the main UCPB processor for use in the control sequence.⁸
• Redundancy: In a standard Mark V system, this board would be replicated in the R1, R2, and R3 cores to support the system’s Triple Modular Redundancy (TMR) architecture, ensuring reliable operation even if one board fails.
