The GE DS200UDSAG1A is a specialized Printed Circuit Board (PCB) used within the General Electric Speedtronic Mark V Turbine Control System.1
Despite its common market designation as an “Excitation Board,” its primary function is actually to serve as a Display/Keyboard Interface Board.2
💻 Function and Role
The DS200UDSAG1A board is responsible for handling the local operator interface for a control module within the Mark V system, specifically dealing with the excitation control process for a generator.
- Interface Management: It manages the interaction between the operator and the control system through a display and keypad.3
- Signal Processing: The board features an onboard 80196 microprocessor which is the main control unit, executing instructions and processing incoming and outgoing control and status signals.4
- Excitation Control: While its general function is an interface, it is specifically applied to the excitation control part of the turbine-generator system, which is critical for regulating generator voltage and power output.5
📊 Key Features and Specifications
The board is equipped with several components to provide diagnostic and control functionality:6
- Microprocessor: Features a powerful 80196 microprocessor for signal management.7
- Visual Feedback: It provides local operational status information via:
- Multiple 4-character displays (some revisions, like the DS200UDSAG1ADD, are reported to have 21 displays).8
- 32 LEDs (Light Emitting Diodes) for quick diagnostic status.9
- Multiple 4-character displays (some revisions, like the DS200UDSAG1ADD, are reported to have 21 displays).8
- Memory: It includes Erasable Programmable Read-Only Memory (EPROM) modules to store essential program code and data.10
- Connections: It includes connectors, such as a 40-pin connector, for signal transmission and reception from other boards and devices.11
- Configuration: The board is populated with jumpers that allow for different hardware configurations and settings.12
The DS200UDSAG1A is a specific revision (indicated by the final ‘A’) of the 13$\text{DS200UDSA}$ board, part of the legacy Mark V series used in the control and management systems of gas, steam, and wind turbines.14
