About the DS200TBQBG1ACB

The DS200TBQBG1ACB is an Analog Termination Board originally designed and manufactured by General Electric for use in their Mark V Turbine Control System Series. This legacy series has been widely applied in the control and management systems of wind, steam, and gas turbine automated drive assemblies. Although the Mark V Series is now obsolete, this board remains in demand due to its incorporation of GE’s patented Speedtronic control system technology.

While the DS200TBQBG1ACB is a highly revised model within the Mark V Series, it is not the original Analog Termination Board of this function — that title belongs to the parent DS200TBQBG1 board, which lacks the three significant revisions present in this model.

Hardware Tips and Specifications

• The DS200TBQBG1ACB features 2 terminal blocks, each with 77 terminals, for a total of 154 signal wire connections.

• The board also includes 15 jumpers, 3 34-pin connectors, and 3 16-pin connectors.

• These terminals connect copper signal wires to other components and boards within the drive assembly, handling signal input and transmission.

• Factory documentation details the signals assigned to each terminal, essential for correct installation and wiring.

• The board’s jumpers, labeled BJ1 through BJ15, serve various configuration functions:

• BJ1-BJ4: Fan out a pressure transducer

• BJ5-BJ7: Install a burden resistor for the pressure transducer

• BJ8-BJ15: Handle analog input configuration

Installation Notes

• Terminal blocks are labeled TB1 and TB2, with each terminal numbered individually (e.g., TB1-66 refers to terminal 66 on terminal block 1).

• When replacing the board, mark each signal wire with its terminal ID using masking tape or tags.

• Loosen terminal screws with a screwdriver to release wires, then secure them to the corresponding terminals on the replacement board.

• All connectors on this board have factory-printed labels. Key connectors include:

• JGQ: TCQA Board Various Signals Connector

• JHR: TCQC Board Pulse Rate and Detection Signals Connector

• JGS/T and JHS/T: Vestigial connectors not normally accessed in use

This detailed labeling and jumper configuration makes the DS200TBQBG1ACB a flexible and critical component within the GE Mark V Speedtronic control systems.
