FUNCTIONAL DESCRIPTION:
IS200TBQBH1A is an Input Termination Module manufactured and designed by General Electric as part of the Mark VI Series used in GE Speedtronic Gas Turbine Control Systems. The Input Termination Module (TBQBH1A) is situated in position seven within both the R2 and R3 cores. In the R2 core, the TBQB board establishes connections to the TCQA and TCQC boards located in the R1 core. Conversely, in the R3 core, the TBQB connects to the TCQA and TCQC boards within the same R3 core. This module is designed to manage various input signals, including voltage, vibration, and pulse rate signals. TBQB terminal board passes through the TCQC board via the JH connector. Additional magnetic pick-up pulse rate signals are available on the QTBA board and are read by the JGG connector. Some of the signals landed on the PTBA terminal board could be landed on the QTBA terminal board and should not be used on both. The corresponding screws on the QTBA terminal board are not available if the signals are also landed on the PTBA terminal board.
TBQBH1A CONNECTIONS:
The module interfaces with the control system through two main connectors, JGR and JHR, which manage all critical input signals for the R2 and R3 cores. The JGR connector is responsible for transmitting vibration signals as well as analog current and voltage inputs to the TCQA boards. These signals include data from sensors and transducers that monitor turbine conditions, enabling precise control and real-time feedback for system operation. The JHR connector handles pulse rate input signals and compressor stall detection signals, sending them to the TCQC boards in the respective cores. This ensures accurate monitoring of rotational speeds, pulse-based events, and compressor performance. Together, JGR and JHR maintain reliable communication between the field devices and control boards, with diagnostics continuously monitoring signal integrity to prevent errors and maintain safe turbine operation.
HARDWARE CONFIGURATION:
BJ1 to BJ4: These connectors are used in older applications to distribute the pressure transducer 1 input signal, which is used for compressor stall detection.
BJ5 to BJ7: When used in conjunction with BJ1 to BJ4, these connectors allow for the installation of a burden resistor on the pressure transducer #1 input signal. This modification converts the signal from a voltage to a current format.
BJ8 to BJ15: These connectors are used to configure the analog input signals, allowing them to be set as either current or voltage inputs.

What is the IS200TBQBH1A?
The IS200TBQBH1A is an Input Termination Module for GE Mark VI Speedtronic systems. It processes voltage, current, vibration, and pulse rate signals from sensors and transducers, sending them to TCQA and TCQC boards in R2 and R3 cores for precise turbine control.
How are signals transmitted through TBQBH1A?
The JGR connector transmits vibration and analog signals to TCQA boards, and the JHR connector sends pulse rate and stall detection inputs to TCQC boards. This ensures accurate signal communication across cores.
How are signals transmitted and processed within the module?
Analog and vibration signals from JGR are routed to the TCQA boards, while pulse rate and stall detection signals from JHR are directed to the TCQC boards. Internal connections via the PTBA, QTBA, and TBQB terminal boards ensure signals are correctly landed without duplication, maintaining signal integrity across cores.
