The GE IS200TBAIH1CCC is a Mark VI Analog Input Terminal Board used to organize and interface analog field signals within a GE Mark VI turbine control system. It forms part of the terminal-board layer between field instrumentation and the control system’s I/O electronics.
In a typical Mark VI installation, signals from process transmitters and other analog instruments are brought into the control cabinet through field wiring. The IS200TBAIH1CCC provides the termination and interface point for these incoming signals before they are routed into the associated Mark VI control and I/O architecture.
The board is particularly relevant in turbine control applications where multiple analog measurement circuits must be brought into an organized cabinet-level termination arrangement. It supports structured wiring, easier channel identification, and maintenance access while keeping field connections separated from the primary control electronics.

The IS200TBAIH1CCC operates as part of the analog input signal path in the Mark VI system. Field instruments generate analog process signals that enter the control cabinet through field wiring and are brought to the terminal board.
The terminal board provides the physical termination and routing interface for these incoming circuits. From there, the corresponding signals continue toward the associated Mark VI I/O electronics for acquisition and processing by the control system.
Field transmitter / instrument → Field wiring → IS200TBAIH1CCC → Mark VI I/O electronics → Control processor
The board itself should be treated primarily as a termination and interface component. It does not replace the processing functions of the Mark VI controller or the associated analog I/O electronics.
For maintenance, the terminal-board arrangement also provides a practical point for tracing field circuits, checking wiring continuity, and identifying connections associated with individual analog measurement channels.
The IS200TBAIH1CCC occupies the field termination layer of the Mark VI analog input architecture. It connects incoming instrumentation wiring with the system’s I/O interface while keeping field termination physically organized within the control cabinet.

The IS200TBAIH1CCC serves as an analog input terminal and interface board within a GE Mark VI system. It provides the connection point between incoming field instrumentation wiring and the associated Mark VI I/O architecture.
The terminal board should not be treated as the primary analog signal-processing device. Its main role is to terminate and route field signals toward the associated Mark VI I/O electronics, where signal acquisition and processing take place.
The field instrument, wiring continuity, terminal connections, associated I/O interface, and corresponding Mark VI configuration should be checked in sequence. Loose or incorrectly identified field connections can prevent the expected measurement from reaching the I/O hardware.
It provides a structured boundary between field instrumentation and the control-system electronics. This arrangement makes field wiring easier to identify, inspect, troubleshoot, and maintain without treating the terminal interface as part of the primary control-processing hardware.
