GE DS200TBQAG1A

Overview

Temperature feedback is essential for monitoring turbine performance and protecting critical equipment. The GE DS200TBQAG1A serves as a thermocouple termination board in the Mark V SPEEDTRONIC control platform. It connects field temperature sensors to the associated signal-processing hardware.

The board organizes thermocouple inputs into separate groups and provides dedicated connectors for signal routing. Integrated cold junction compensation supports thermocouple measurement by accounting for the reference-junction temperature.

Main Functions

• Terminates field thermocouple wiring.

• Routes temperature signals to compatible processing boards.

• Supports up to 45 input channels in applicable configurations.

• Provides three signal interfaces identified as JAR, JAS, and JAT.

• Supports temperature monitoring in turbine control applications.

Hardware and Configuration

The assembly includes two terminal blocks, multiple ribbon cable interfaces, and electronic circuitry for thermocouple signal handling. Each connector carries a designated group of temperature signals to compatible Mark V hardware.

The exact channel assignment can vary with the controller configuration. Therefore, engineers should consult the relevant GE wiring diagrams before installation or replacement.
