The GE DS200TCPAG1A Turbine Control Processor Board is the central computing unit—the brain—for one of the control channels in the General Electric Speedtronic Mark V Turbine Control System.1
🧠 Core Function and Role
The DS200TCPAG1A (TCPA for Turbine Control Processor Assembly/Board) is the main printed circuit board (PCB) that executes the control logic for the gas or steam turbine.2
- System Core: It is installed within one of the redundant cores of the Mark V panel, responsible for running the application-specific code (control sequence programming, or CSP) that manages all turbine operations.3
- Primary Function: Its core responsibility is real-time control, monitoring, and fault detection. This includes calculating fuel demands, positioning servo valves, reading all sensor inputs (temperatures, pressures, speeds), and managing the overall turbine start-up, operation, and shutdown sequences.
- Redundancy: In a Triple Modular Redundant (TMR) Mark V system, three such processor boards would operate in parallel, one for each “T,” “R,” and “S” core. The outputs are subject to a two-out-of-three voting process to ensure high reliability and fault-tolerance, which is a hallmark of the Mark V system.

🔄 Revisions
The part number DS200TCPAG1A indicates the specific revision of the board:
- DS200TCPA: Core part name (Control Processor Board).5
- G1A: Indicates the Group 1 Assembly and the initial Functional Revision ‘A’.6
Later revisions of the board (e.g., DS200TCPAG2A or DS200DCPAG1A, an auxiliary processor board) offer functional enhancements, but the core function of the DS200TCPAG1A is to be the primary brain for one channel of the turbine’s control and protection system.
