Overview

The DS200TCQCG1BHF is an Analog I/O Expander Board designed by General Electric for the Mark V Series. It is primarily used in gas and steam turbine control systems, specifically for medium- to large-duty turbines. This board features a triple-redundant system for critical control backup, making it a key component in the EX2000 subset of the Mark V Series.

Hardware Features

• Connectors:
  • 11 vertical pin cable connectors
  • 5 male vertical pin header connectors
  • 1 female vertical plug
• Components:
  • 6 relay components
  • Over 25 resistor network arrays
  • 40+ integrated circuits
  • Ceramic capacitors, diodes, and metal film resistors
• Jumpers: 37 jumper switches (important to replicate jumper settings from the previous board)
• Heat Sink: Included for heat dissipation
• Mounting: Drilled in each corner for mounting, with edge markings for proper alignment

Functional Description

• Primary Function: Provides excitation to the LVDT (Linear Variable Differential Transformer) and LVDR (Linear Variable Differential Resistor).
• Redundancy: Part of a triple-redundant system using R/S/T processors for multiple backups in critical control systems.

Installation Notes

• Alignment: Ensure proper positioning and alignment of connectors and jumpers during installation.
