The Mark VIe I/O modules consist of three basic parts, the terminal board, the terminal block, and an I/O pack. Barrier or box-type terminal blocks are mounted on a terminal board, which mounts on a DIN rail or base in the control cabinet. The I/O pack contains two Ethernet ports, a power supply, a local processor, and a data acquisition board. I/O capability grows as I/O packs are added to the control system, enabling use in a simplex, dual, or triple redundant configuration. Some process sub-systems require even more throughput. Therefore, the local processors in each I/O pack run algorithms at higher rates as required for the application.

When using the IS200TDBTH2ACD terminal board, ensure correct polarity and secure wiring of the excitation voltage (typically 24 VDC) to prevent input failures. In TMR configurations, strictly verify the mapping between the three I/O packs and the JR1/JS1/JT1 connectors, never touch high-voltage relay components while energized, and utilize ToolboxST software to regularly monitor status alarms to ensure consistency in the system's voting logic.
It is a discrete input/output terminal board used in the GE Mark VIe control system to handle on/off signals.
