Product Overview
The GE IS200TBAOH1CCB is a Mark VI Analog Output Terminal Board used to organize and terminate analog output circuits within a GE Mark VI turbine control system. It forms part of the field-side interface between the Mark VI I/O architecture and analog-controlled devices installed in the turbine or plant.
In a typical Mark VI installation, the control system generates an analog command through its I/O hardware, while field devices such as control elements receive the corresponding signal through cabinet wiring. The IS200TBAOH1CCB provides the terminal interface that organizes these outgoing circuits before they continue toward the field.
This terminal-board arrangement keeps field wiring structured and provides a defined point for connection inspection and troubleshooting. It is suited to established Mark VI turbine control cabinets where analog output circuits need to be terminated and routed in an organized manner.

Working Principle
The IS200TBAOH1CCB forms part of the analog output path from the Mark VI control system toward field equipment. The control processor determines the required control action, and the corresponding command is delivered through the Mark VI I/O hardware.
The output signal then reaches the IS200TBAOH1CCB, where the associated field circuit is terminated and routed toward the connected field device. Depending on the application, the receiving device may be an actuator, control element, or other equipment requiring an analog command.
Control processor → Mark VI I/O electronics → IS200TBAOH1CCB → Field wiring → Analog-controlled device
The terminal board primarily handles the physical interface and routing of the output circuits. It does not replace the control logic executed by the Mark VI controller or the I/O functions that generate and manage the analog output signal.
During troubleshooting, the complete signal path can be checked from the control command through the I/O interface, terminal connections, field wiring, and receiving device. This helps distinguish a terminal or wiring issue from a problem in the control or I/O section.
Role in a GE Mark VI Turbine Control Architecture
The IS200TBAOH1CCB occupies the field termination layer of the Mark VI analog output architecture. It provides the connection boundary between the electronic I/O section and external analog-controlled equipment.

| Turbine Control | GE Mark VI Controller | Executes turbine control strategies and output commands |
| Control Processing | Mark VI Control Processor | Determines control actions from configured logic and process conditions |
| I/O Interface | Mark VI Analog Output Hardware | Generates and manages analog output signals |
| Termination | IS200TBAOH1CCB | Terminates and routes analog output field circuits |
| Field Interface | Actuators / Control Devices | Receives analog control commands |
| Turbine Process | Gas or Steam Turbine Equipment | Responds to the commanded control action |
Industrial Applications

Installation and Maintenance
- Confirm that the IS200TBAOH1CCB matches the existing Mark VI analog output termination 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 outgoing field connections before removing the existing terminal-board wiring.
- Inspect terminals and board interfaces for contamination, corrosion, looseness, or physical damage.
- Check associated output wiring for damaged insulation, overheating, abrasion, or mechanical stress.
- Install the board in the correct cabinet position and maintain the established wiring arrangement.
- Ensure all output connections are fully seated and mechanically secured.
- Verify every field connection against the applicable Mark VI documentation before energizing the circuit.
- Check the corresponding analog output channels for abnormal behavior or unexpected output conditions after installation.
- If an output does not reach the field device as expected, trace the circuit from the I/O hardware through the terminal board and field wiring.
- Record the installed board model and associated output-circuit wiring for future Mark VI maintenance and troubleshooting.

Technical FAQs
What is the primary function of the IS200TBAOH1CCB?
The IS200TBAOH1CCB serves as an analog output terminal and interface board within a GE Mark VI system. It provides the physical connection between Mark VI analog output circuits and the associated field devices.
Does the IS200TBAOH1CCB generate the analog output signal?
The terminal board should be treated primarily as a termination and routing component. The associated Mark VI analog output I/O hardware handles the electronic output function, while the terminal board provides the field-side connection.
What should be checked if a field actuator does not respond to an analog command?
The control command, associated I/O channel, terminal-board connections, field wiring, and receiving device should be checked in sequence. This helps determine whether the issue is located in the control system, I/O interface, terminal connection, or field circuit.
Why is an analog output terminal board useful in a Mark VI system?
It provides a structured connection point between the electronic I/O section and field equipment. This simplifies cabinet wiring organization and gives maintenance personnel a defined location for checking and tracing analog output circuits.
