The GE DS3800HPIB is a specialized Panel Interface Card used in the GE Speedtronic Mark IV series of turbine control systems. It is a legacy part, 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 DS3800HPIB 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 has built-in diagnostic features and indicator LEDs to provide a quick visual status of its health and activity.
Technical and Design Features
The DS3800HPIB 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.
- Memory: The board contains both EPROMs and EEPROMs, which are used to store the board’s firmware and configuration data. The EPROMs can be updated as needed, while the EEPROMs are fixed.
- Connectors: The board has multiple connectors, including eight terminals on each side, that allow it to interface with other circuit boards and system components in the control rack.
- Jumpers and Resistors: It is equipped with jumpers and resistors that allow technicians to configure its operational settings to match the specific requirements of a given application.
- Physical Features: It features a number of visual indicators, including around 50 blue LEDs that light up according to the programming, and six silver diodes.
