GE DS200UDSAG1ACC Gas Turbine Excitation Board

الوصف

The GE DS200UDSAG1ACC is a Display/Keyboard Interface Board (UDSA) that is a component of the General Electric Speedtronic Mark V Turbine Control System, often used within the associated Excitation Control System (like the EX2000 or EX2100) for gas and steam turbines.¹

While it’s often referred to as an “Excitation Board” due to its application, its core function is to serve as the Human-Machine Interface (HMI) for the operator to monitor and control the excitation process locally.²

⚙️ Board Function and Features

The $\text{DS200UDSAG1ACC}$ board handles the local input and display functions for the excitation control module in the GE Mark V system.

• System Role: It is a ³$\text{DS200}$ series circuit board, which belongs to the larger, highly reliable GE Speedtronic Mark V control system architecture that uses Triple Modular Redundancy (TMR) for critical functions.⁴
• UDSA Abbreviation: The ⁵$\text{UDSA}$ in the part number stands for Universal Display Station Assembly or Display/Keyboard Interface.⁶
• Operator Interface: It is the primary way maintenance personnel and operators interact directly with the excitation control portion of the system.⁷
• Microprocessor: The board incorporates a microprocessor (e.g., an 80196 in similar revisions) to execute local control logic, manage the display, and process inputs.⁸

The part number’s suffix, $\text{ACC}$, indicates a specific software or firmware revision of the $\text{DS200UDSAG1A}$ hardware configuration.
