GE DS200TBQDG1 RST Extension RST Analog Termination Board

GE DS200TBQDG1 RST Extension RST Analog Termination Board

GE DS200TBQDG1 is an RST Extension Analog Termination Board (often abbreviated as TBQD) for the General Electric Mark V Speedtronic Turbine Control System.

Its main function is to provide extended analog I/O termination capacity for the Mark V system, primarily connecting signals that require isolation or are part of an expanded I/O configuration.

 

Key Functions and I/O Types

 

The TBQD board is a high-density field-wiring termination module that extends the capability of the main analog acquisition board (TCQA/TCQB) in the Mark V control cores.

I/O Type Primary Function Description
LVDT Inputs Position Measurement Terminates signals from Linear Variable Differential Transformer (LVDT) sensors used for precise control valve and actuator positioning.
Proximitors Vibration Monitoring Terminates inputs from proximity probes (Proximitors) used to measure shaft vibration and displacement, which is crucial for turbine protection.
Analog Outputs (mA) Auxiliary Control/Monitoring Terminates analog current output signals from the controller for auxiliary functions.

Technical and Physical Details

 

  • System Series: GE Mark V Speedtronic Turbine Control System (used in gas, steam, and wind turbine control).
  • Designation: The functional acronym TBQD stands for Termination Board for Quick Connect (D-version, which is typically an extension board). The ‘RST Extension’ in the name confirms its role in providing supplementary I/O to the main control cores.
  • Terminals: The board is physically characterized by its high-density termination points, featuring two terminal blocks, with some revisions containing 107 terminals each for signal wires.
  • Jumpers: The board includes a few hardware jumpers (commonly identified as BJ1 and BJ2) that allow a qualified technician to configure board settings or define processing requirements for the specific turbine drive application.
  • Protective Components: It includes components like metal oxide varistors (MOVs) to provide overvoltage protection, shunting excessive voltage away from sensitive internal circuitry.
  • Connectivity: It uses connectors, such as 34-pin or 50-pin ribbon cable connectors, to interface with other boards, particularly the main I/O boards in the R, S, and T (Triple Modular Redundant) cores.
