Product Overview
The GE IS210DTAIH1A / IS200DTAIH1A is a Mark VI Simplex Analog Input/Output Terminal Board used to connect analog field circuits with the GE Mark VI turbine control system. It belongs to the field-interface portion of the Mark VI architecture, providing an organized termination point between field wiring and the associated analog I/O hardware.
The board is used where analog process measurements or control signals need to pass between field equipment and the Mark VI control system. Depending on the configured circuit, field instrumentation can provide an analog measurement to the control system, while analog output commands can travel in the opposite direction toward an applicable field device.
The IS210DTAIH1A / IS200DTAIH1A is relevant to turbine control maintenance, control cabinet refurbishment, and replacement of existing terminal hardware. During service, the terminal assignments, I/O channel mapping, connected field circuits, and associated Mark VI configuration should be checked together to avoid wiring or channel-assignment errors.

Working Principle
The IS210DTAIH1A / IS200DTAIH1A serves as the physical termination interface for analog input and output circuits in a GE Mark VI system. For an analog input, a field transmitter or other analog instrument generates an electrical signal corresponding to a measured process condition. The field wiring carries that signal to the terminal board, where the circuit is connected and routed toward the associated Mark VI I/O hardware.
The electronic I/O hardware then acquires the analog signal and makes the resulting information available to the Mark VI control system for monitoring, control, alarm, or protection functions according to the configured application.
The input path can be represented as:
Analog Field Device → Field Wiring → IS210DTAIH1A / IS200DTAIH1A → Mark VI Analog I/O Hardware → Mark VI Control System
For analog outputs, the signal path operates in the reverse direction:
Mark VI Control System → Mark VI Analog I/O Hardware → IS210DTAIH1A / IS200DTAIH1A → Field Wiring → Analog Control Device
The terminal board itself does not independently execute turbine control logic. Its primary role is to provide the physical electrical interface between field circuits and the associated I/O system.
When an analog channel shows an abnormal value, troubleshooting should include the complete circuit. Field wiring, transmitter or control device, terminal connections, I/O hardware, and Mark VI configuration can all influence the final signal.

Installation and Maintenance
- Verify the board identification — Confirm that IS210DTAIH1A / IS200DTAIH1A matches the existing Mark VI documentation and required replacement position.
- Review the analog I/O documentation — Check wiring diagrams, terminal assignments, loop drawings, I/O channel mapping, and applicable control-system documentation.
- Isolate the affected circuits — Follow the approved plant procedure to place the relevant control and field circuits in a safe maintenance condition.
- Identify analog connections — Label or record each field connection before disconnecting the existing terminal board to preserve the correct channel assignments.
- Inspect the replacement board — Check terminals, connectors, mounting features, and accessible surfaces for physical damage or contamination.
- Inspect field wiring — Examine analog signal conductors for loose connections, damaged insulation, corrosion, or other conditions that could affect signal quality.
- Remove the existing board carefully — Apply appropriate ESD precautions and avoid unnecessary mechanical force on terminals, connectors, or mounting hardware.
- Install the replacement board — Position the IS210DTAIH1A / IS200DTAIH1A correctly within the Mark VI terminal arrangement and secure it according to the applicable cabinet configuration.
- Reconnect analog circuits — Restore each conductor to its documented terminal position and verify that all connections are mechanically secure.
- Verify channel assignments — Confirm that field circuits correspond to the correct Mark VI I/O channels and configured input or output functions.
- Perform a controlled signal check — Restore the affected circuits and verify expected analog readings or output responses without unexpected alarms or signal faults.
- Document the maintenance activity — Record the board designation, terminal assignments, connected circuits, test results, and any changes made during replacement.
