The GE DS3800XTFH is a Pulse Distribution Card for the GE Speedtronic Mark IV turbine control system. It’s a key component responsible for taking a timing signal and distributing it to various parts of the control system. This ensures that different functions and components operate in precise synchronization.
Function and Purpose
In a turbine control system, precise timing is critical for everything from fuel combustion to controlling speed and load. A pulse distribution card like the DS3800XTFH ensures that a master timing pulse is accurately and reliably delivered to the necessary modules. This can involve:
- Signal Replication: It takes a single pulse signal and creates multiple identical copies to send to other cards.
- Signal Buffering: It isolates the master timing source from the rest of the system, so if there’s a problem in one module, it won’t affect the master clock.
- Driving Logic: The distributed pulses can be used to drive sequential logic, where a series of actions must happen in a specific order and at a specific time.
This function is essential for the real-time processing and control of turbine operations, as it maintains system efficiency and reliability. The card is designed to integrate seamlessly into the modular Mark IV system, allowing for easy installation and maintenance.
Technical Specifications (Inferred)
Detailed specifications for the DS3800XTFH are not widely available due to the age of the Mark IV system. However, based on its function and series, we can infer some key attributes:
- Part Number: DS3800XTFH
- Series: GE Speedtronic Mark IV
- Product Type: Pulse Distribution Board
- Function: Distributes precise timing pulse signals
- Application: Turbine control systems and related processes.
Related Components
As a pulse distribution card, the DS3800XTFH works in conjunction with many other components of the Mark IV system, including:
- Processor Cards: The main CPU of the system receives the timing signal from a master clock and uses the DS3800XTFH to distribute it to other modules.
- I/O (Input/Output) Cards: These cards use the distributed pulses to time their data acquisition or control actions, such as sampling sensor data or energizing a relay.
- Backplane: The card plugs into the system’s backplane (e.g., the DS3800XCIB), which provides the power and electrical pathways for communication.
