GE DS200TBQCG1A TERM BD(R-S-T) ANALOG I/O

  • Obsolete Status: As a component of the discontinued Mark V series, the DS200TBQCG1A is considered an obsolete part. It is no longer manufactured by GE and is typically sourced from new old stock, surplus vendors, or specialized repair and refurbishment companies.
  • Limited Diagnostics: The board itself has limited diagnostic features, such as a lack of test points and indicator LEDs. However, the Mark V system’s internal diagnostic tools, which are stored in the system’s PROM, can be used to troubleshoot and diagnose problems with the board.

الوصف

The GE DS200TBQCG1A is a specialized circuit board known as a RST Analog I/O Termination Board. It’s a component of the legacy GE Speedtronic Mark V series of industrial control systems, which are used to control turbines in power generation.

 

Key Features and Function

 

  • Analog I/O Termination: The board’s main function is to serve as a high-density termination point for analog input and output signals. These signals are from various field devices like pressure transducers and voltage sensors, which provide continuous measurements.
  • Triple-Redundant System (R-S-T): The “(R-S-T)” in the part number indicates that the board is designed for the triple-redundant architecture of the Mark V system. This means it provides inputs and outputs to all three (R, S, and T) of the system’s processors, ensuring fault tolerance and high reliability.
  • High-Density Connectivity: The board features two terminal blocks, each with 77 terminals, allowing for a total of 154 signal wire connections. It also includes 15 jumpers and several multi-pin connectors for communication with other boards in the system.
  • Obsolete Status: As a component of the discontinued Mark V series, the DS200TBQCG1A is considered an obsolete part. It is no longer manufactured by GE and is typically sourced from new old stock, surplus vendors, or specialized repair and refurbishment companies.
  • Limited Diagnostics: The board itself has limited diagnostic features, such as a lack of test points and indicator LEDs. However, the Mark V system’s internal diagnostic tools, which are stored in the system’s PROM, can be used to troubleshoot and diagnose problems with the board.
