GE DS3800HPIA MKIV, Panel Interface Card

 

The DS3800HPIA is a robust, industrial-grade circuit board designed to operate in a demanding environment.

  • Legacy Part: The “DS3800” prefix indicates that it belongs to the legacy Mark IV series, which was GE’s first microprocessor-based gas turbine control system, introduced in the 1980s.
  • Connectors: The board features two 34-pin connectors and a 20-pin connector that allow it to interface with other boards and system components in the control rack.
  • Jumpers and Trimmers: It is equipped with jumpers and trimmer resistors that allow technicians to configure its operational settings to match the specific requirements of a given application.
  • Physical Features: It has two extractor clips on the front corners to make it easy to insert and remove from its slot.

الوصف

The GE DS3800HPIA is a specialized Panel Interface Card used in the GE Speedtronic Mark IV series of turbine control systems. As a legacy part, it’s no longer in production and is primarily found on the surplus and refurbished markets for the maintenance of older systems.


 

Function and Purpose

 

The primary function of the DS3800HPIA is to serve as the communication and control link between the main control rack and the human-machine interface (HMI) on the front panel. This panel typically includes displays, buttons, and switches that allow an operator or technician to monitor and interact with the turbine control system. Its key roles include:

  • Data Interface: The board facilitates the transfer of data from the main control processors to the display on the panel. This includes real-time operational data, status messages, and alarms.
  • Input Processing: It processes commands from the operator, such as button presses or switch positions, and sends them to the main processors for execution. This is critical for tasks like starting or stopping the turbine, acknowledging alarms, or changing setpoints.
  • Signal Conditioning: The card conditions the signals to ensure they are clean, stable, and free from the electrical noise inherent in an industrial environment.
  • System Diagnostics: The card likely has built-in diagnostic features and indicator LEDs (two red and one amber) to provide a quick visual status of its health and activity.

Applications and Importance

 

The DS3800HPIA is a fundamental component of the GE Mark IV system’s human-machine interface. Its importance lies in its ability to provide a direct communication and control link between the operator and the control system. Without this board, it would be difficult or impossible to interact with the turbine and monitor its status from the control panel.
