The GE DS3820AIPB is an Analog Terminal Board for the GE Speedtronic Mark IV turbine control system. It’s an Input/Output (I/O) card that handles signals with a continuous range of values, such as temperature and pressure.
Function and Purpose ⚙️
The primary role of the DS3820AIPB is to provide a physical interface and signal conditioning for analog signals. It serves as a connection point between the external world of sensors (like thermocouples, pressure sensors, and flow meters) and the system’s electronic control cards. The board takes the continuous analog signals from these field devices and converts them into a format that the system’s main processor can read and use. This process involves:
- Signal Conditioning: The board includes circuitry to filter and protect signals from electrical noise and voltage spikes that are common in industrial environments. This ensures the data is accurate.
- Physical Connection: It provides a robust, screw-terminal interface for field wiring, which simplifies installation and maintenance.
Related Components
The DS3820AIPB works with other Mark IV system components.
- Processor Cards: The main CPU, such as the DS3800HCDA, receives the converted digital data from the DS3820AIPB.
- Backplane Cards: It plugs into the system’s backplane (e.g., the DS3800XCIB), which provides it with power and a data bus to communicate with other modules.
- Sensors and Actuators: It receives signals directly from various analog sensors and transmits them to the control system.
