GE DS200TBQBG1A Input Termination Module

الوصف

The GE DS200TBQBG1A is an Input Termination Module (functional acronym $\mathbf{TBQB}$) for the General Electric (GE) Mark V Speedtronic Turbine Control System. It is essentially an Analog Termination Board used to interface various types of analog input signals from the turbine to the control system’s main processing boards.

Function and Features

The primary purpose of the $\text{DS200TBQBG1A}$ is to provide a reliable termination point and conditioning for specific non-thermocouple analog signals.

• Signal Termination: It serves as the physical connection point for field wiring carrying analog signals.
• Terminated Signals: The board is designed to receive and terminate specific input signals, including:
  • Voltage ($\text{DC}$ voltage) and Analog Current ($\text{mA}$ signal) inputs.
  • Vibration transducer signals.
  • Pulse Rate inputs (e.g., from magnetic pickups for speed or flow).
  • Compressor Discharge Transmitters.
• Signal Routing: It routes these terminated signals to the main $\text{Mark V}$ processing boards, such as the $\text{TCQA}$ and $\text{TCQC}$ boards, which handle the Analog and Pulse Rate inputs, respectively.
• Configuration: The board often includes a set of jumpers (e.g., $\text{BJ1}$ through $\text{BJ15}$) which allow technicians to configure the settings for the analog inputs, such as selecting between a voltage or current ($\text{mA}$) signal type.

Hardware Specifications

• Product Series: GE Mark V Speedtronic.
• Functional Acronym: $\text{TBQB}$.
• Terminal Blocks: It features two terminal blocks, typically with 77 terminals each (totaling $154$ terminals) for connecting signal wires from the field devices.
• Connectors: The board includes multiple connectors for communication with the control core, such as $34\text{-pin}$ and $16\text{-pin}$ connectors.
• Location: In the $\text{Mark V}$ cabinet, the $\text{TBQB}$ board is often located in a specific position (e.g., location $7$ or $8$) within the redundant control cores ($\text{R}$, $\text{S}$, or $\text{T}$).
