Product Overview
The GE IS200TBAIH1CDC is a Mark VI Analog Input Terminal Board used to terminate and organize analog field signals within a GE Mark VI turbine control system. It forms part of the cabinet-level interface between field instrumentation and the system’s analog I/O hardware.
In a typical turbine control installation, transmitters and other process instruments send measurement signals through field wiring into the control cabinet. The IS200TBAIH1CDC provides the termination point for these circuits and routes the associated connections toward the Mark VI I/O electronics.
The board is suited to established Mark VI installations where analog instrumentation must be arranged in a structured and maintainable cabinet architecture. Its role is focused on field termination and signal interconnection rather than control logic or primary signal processing.

Working Principle
The IS200TBAIH1CDC forms part of the analog input signal path between field instrumentation and the Mark VI control system. A field transmitter or sensor produces a process measurement, and the corresponding electrical signal travels through the plant’s field wiring toward the control cabinet.
The signal is terminated at the IS200TBAIH1CDC, where the field connection is organized and routed toward the associated Mark VI I/O interface. The I/O hardware then acquires the signal for use by the control system.
Field transmitter / sensor → Field wiring → IS200TBAIH1CDC → Mark VI I/O electronics → Control processor
The terminal board itself is not the primary control processor. Its function is centered on physical termination and signal interconnection, making it part of the boundary between field instrumentation and electronic I/O processing.
During troubleshooting, this signal path provides a logical sequence for checking an abnormal measurement. Technicians can work from the field device through the wiring and terminal connections toward the I/O hardware to determine where the expected signal is interrupted or degraded.
Role in a GE Mark VI Turbine Control Architecture
The IS200TBAIH1CDC occupies the field termination layer of the Mark VI analog input architecture. It connects plant instrumentation wiring with the corresponding I/O interface while maintaining an organized cabinet-level wiring structure.

Installation and Maintenance
- Confirm that the IS200TBAIH1CDC matches the existing Mark VI terminal-board arrangement before installation.
- Review the applicable cabinet drawings and field wiring documentation before disconnecting the existing board.
- Isolate the relevant control and I/O circuits according to the plant’s electrical safety and maintenance procedures.
- Identify and label field connections before removing the existing terminal-board wiring.
- Inspect terminals and board interfaces for corrosion, contamination, looseness, or physical damage.
- Check associated wiring for signs of overheating, abrasion, or mechanical stress.
- Install the terminal board in the correct cabinet position and maintain the established wiring layout.
- Ensure field connections are fully seated and mechanically secured.
- Verify each connection against the applicable Mark VI wiring documentation before energizing the system.
- Check the corresponding analog input channels for abnormal readings, missing measurements, or unexpected signal changes.
- If a channel remains abnormal, trace the signal from the field instrument through the wiring and terminal interface to the associated I/O hardware.
- Record the installed board model and wiring arrangement for future Mark VI maintenance and troubleshooting.

Technical FAQs
What is the role of the GE IS200TBAIH1CDC in a Mark VI system?
The IS200TBAIH1CDC serves as an analog input termination and interface board. It connects incoming field instrumentation wiring with the associated Mark VI I/O architecture.
Where does the analog signal go after reaching the terminal board?
After field wiring reaches the IS200TBAIH1CDC, the corresponding signal is routed toward the associated Mark VI I/O electronics. The I/O hardware acquires the signal and makes the measurement available to the control system.
What symptoms can indicate a problem around the terminal-board connection?
A missing or abnormal analog measurement can result from issues anywhere along the signal path, including field instrumentation, wiring, terminal connections, or associated I/O hardware. Connection inspection and signal tracing should be performed before replacing other system components.
Can the IS200TBAIH1CDC be evaluated independently from the associated I/O hardware?
The terminal board can be inspected for physical condition, connection integrity, and wiring continuity, but proper system-level verification also requires checking the associated field circuit and I/O interface. The terminal board is one part of the complete analog input signal path.
