The IS200TBQBH2A is a Input Termination Module (TBQB) designed and manufactured by General Electric as part of the Speedtronic Mark VI gas turbine control framework. Positioned within the decentralized I/O layer, this board functions as the physical landing zone for critical mechanical feedback instrumentation, specifically routing voltage, vibration, and pulse rate frequency inputs. The H2A revision delivers an upgraded, highly stable board layout optimized to suppress high-frequency noise and safeguard central processing engines from field-side electrical surges.
CORE ROUTING AND INTERFACE DYNAMICS
The physical layout of the IS200TBQBH2A is designed for placement in position seven within the R2 and R3 controller cores. When positioned in the R2 core, the board aggregates external inputs and distributes them to the TCQA and TCQC processing cards located in the R1 core. Conversely, when configured within the R3 core, it forms localized communication loops, connecting directly to the internal TCQA and TCQC processing hardware inside the same R3 core structure.
DUAL CONNECTOR ARCHITECTURE (JGR / JHR)
System interconnectivity is split across two high-density multi-pin arrays to keep disparate signal categories isolated:
HARDWARE CONFIGURATION:
BURDEN RESISTOR AND SIGNAL CONDITIONING HARDWARE
The circuit board features onboard hardware jumpers categorized from BJ1 through BJ7 to allow variable field commissioning adjustments. Jumpers BJ1 to BJ4 are used to split and route the pressure transducer 1 input signal intended for active compressor stall warning logic. When combined with the configuration of jumpers BJ5 to BJ7, the board introduces a hardware burden resistor into the loop. This physical circuit modification converts the primary transducer input from a voltage format into a structured current format, preventing signal degradation over lengthy field wiring runs.
WHY PARTNER WITH WORLD OF CONTROLS
World of Controls provides comprehensive product lifecycle support for heavy power generation facilities running legacy GE Mark VI Speedtronic infrastructure. Every certified IS200TBQBH2A input termination card undergoes exhaustive diagnostic testing inside live, running test panels. We evaluate signal continuity across all 24 channels, verify jumper-configured burden resistor path transitions, confirm noise-free packet delivery over the JGR/JHR interface connectors, and perform thermal performance sweeps. WOC stocks these critical assemblies in both UNUSED and REBUILT profiles.
What is the GE IS200TBQBH2A?
It is an Input Termination Module (TBQB) designed for GE Speedtronic Mark VI control systems. It acts as a dedicated terminal interface that accepts field wiring for vibration, voltage, and high-frequency pulse rate signals, routing them to core processing boards.
Where is this module physically located within the Mark VI control panel?
The module mounts directly onto a standard DIN rail and is specifically positioned in slot/position seven within the R2 and R3 controller cores of the Mark VI cabinet layout.
How does the cross-core signal routing differ between the R2 and R3 installations?
When the board is mounted in the R2 core, it routes its telemetry data across to the TCQA and TCQC cards in the R1 core. When installed in the R3 core, it connects directly to the TCQA and TCQC cards within that same R3 core.
What specific data streams are split between the JGR and JHR faceplate connectors?
The JGR connector routes high-speed vibration signals and general analog current/voltage metrics to the TCQA card. The JHR connector isolates pulse rate inputs (like magnetic speed pickups) and compressor stall indicators, routing them to the TCQC board.
What is the purpose of hardware jumpers BJ1 through BJ7 on the board?
These jumpers configure the input formatting for the primary compressor stall pressure transducer. Jumpers BJ1�BJ4 split the incoming signal, while BJ5�BJ7 switch an internal burden resistor into the path to convert the transducer signal from a voltage format into a current format.
Can the IS200TBQBH2A be used simultaneously with a QTBA terminal board for the same inputs?
No. While some field signals can land on either a PTBA or a QTBA terminal board, the signals must not be duplicated. If a specific input path is wired and terminated on the primary board, the corresponding screw terminals on the auxiliary terminal board are omitted or must be left completely unpopulated.
