GE DS200UDSAG1ADD Control System Excitation Board

الوصف

The GE DS200UDSAG1ADD is a Control System Excitation Board manufactured by General Electric, primarily for use in the Mark V Speedtronic Turbine Control System and its associated generator Excitation Control modules (like the EX2000 or EX2100).

Despite being labeled an “Excitation Board,” its main role is that of a sophisticated Display/Keyboard Interface Board. It is essentially the local Human-Machine Interface (HMI) for the excitation control system.

⚡ Key Function and Technical Specifications

The $\text{DS200UDSAG1ADD}$ board manages the local operator interface, allowing engineers and technicians to monitor and interact directly with the excitation control process for a generator (typically driven by a gas, steam, or wind turbine).

Key Features

• Operator Interface (HMI): It serves as the primary local interface for viewing system status and alarms, as well as making adjustments and running diagnostics.
• Excitation Control: It is a component within the system that performs the excitation control for the generator, which regulates the DC field current to maintain the desired output voltage and reactive power.
• Processor: Features a powerful 80196 microprocessor which executes instructions and manages the display and input scanning.
• Memory: Includes multiple EPROM modules (Erasable Programmable Read-Only Memory) for storing the operating program code and configuration data.
• Visual Feedback: It is typically equipped with:
  • 21 4-character displays for concise, segmented visual feedback.
  • 32 LEDs for quick status recognition and indicators.
• Configuration: The board contains numerous jumpers (e.g., 14 3-pin jumpers) that allow for different hardware configurations and settings, customizing its operational behavior.
