Description
The GE IS200TBCIH1CBC (featuring the IS200TBCIH1C base board layout with Advancements/Conformal Coating revisions denoted by “CBC”) is an analog output terminal board designed for the GE Speedtronic Mark VI gas and steam turbine control systems.
In industrial turbine management applications, this terminal board acts as an interface layer for generating, routing, and distributing analog control signals to actuators, servovalves, and instrumentation panels. It provides built-in signal conditioning, noise filtering, and surge suppression to ensure precise, reliable control in heavy power-generation environments.

Integration and Compatibility Notes
The IS200TBCIH1CBC mounts directly inside Mark VI termination cabinets and interfaces with corresponding control module I/O packs.
- Hardware Revision Suffix (-CBC): The trailing “CBC” characters represent specific manufacturer production revisions, component layout updates, or conformal coating levels. Ensure exact compatibility match with your existing panel wiring scheme and I/O pack firmware.
- No Hardware Jumpers Required: The board design simplifies installation by eliminating manual hardware setup jumpers; configuration parameters are managed via the Mark VI Toolbox/ToolboxST software suite.
- Noise Mitigation: Includes integrated high-frequency filters and surge suppression components to protect sensitive control loops from electrical noise generated by heavy plant machinery and variable drives.
Frequently Asked Questions
Q: What is the primary function of the IS200TBCIH1CBC within the Mark VI architecture? A: It functions as an analog output terminal board, routing control commands from the Mark VI system to critical field devices such as servo valves, actuators, and external indicators.
Q: Can this board be used as a drop-in replacement for older revision boards (e.g., -ABB or -AAC)? A: Generally yes if the core base model matches (IS200TBCIH1C), but you should verify minor revision level changes (-CBC) against your system drawings and software configuration to prevent signal mapping or terminal layout discrepancies.
Q: Does the board require external power connections? A: Operating power and signal loops are routed through the mating I/O packs and cabinet distribution terminal blocks. Always power down the corresponding cabinet section before servicing or swapping terminal boards.
