The GE IS200VAICH1DAA is an Analog Input/Output Board in the Mark VI control system, supporting both simplex and TMR configurations. It handles 20 analog inputs and 4 analog outputs, converting analog signals to digital values for transmission to the controller via the VME backplane, and vice versa for output currents.

In TMR setups, input signals fan out to three VME racks (R, S, T), each with a VAIC; outputs use a proprietary circuit to combine signals from all three, ensuring fault tolerance. In simplex mode, a single VAIC processes all signals. It integrates with TBAI terminal boards via J3/J4 latching connectors, supporting loads up to 800Ω over 1000ft of #18 wire with 18V drive voltage. Part of the Mark VI series, it enhances turbine control with Speedtronic technology.

Features:
I/O Capacity: 20 analog inputs and 4 outputs, managed via two terminal boards.

Redundancy Support: TMR configuration with three VAICs ensures fault tolerance; simplex mode offers streamlined operation.

Signal Processing: Converts analog-digital signals for controller communication and digital-analog for output currents, maintaining integrity over long cables.

Compatibility: Works with TBAI terminal boards, supporting 800Ω loads and 1000ft wiring via 18V drive voltage.

Industrial Adaptability: Integrates with Mark VI systems, enabling compressor stall detection and reliable performance in turbine control applications.

Easy Installation: Connects via J3/J4 latching connectors; diagnostic lights indicate system health post-power-up.
