GE DS3820AIRB MKIV, Analog Terminal Board

The primary role of the DS3820AIRB 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.
  • Signal Conversion: It converts the analog signals from the sensors into digital data that the system’s main processor can read and use to make control decisions.

The DS3820AIRB works with other Mark IV system components.

  • Processor Cards: The main CPU, such as the DS3800HCDA, receives the converted digital data from the DS3820AIRB.
  • 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.
