FUNCTIONAL DESCRIPTION:
IS200VAICH1CAB is an Analog Input/Output (VAIC) Board Manufactured and designed by General Electric as part of the Mark VI Series used in GE Speedtronic Gas Turbine Control Systems. The VAIC board manages 20 analog inputs and controls 4 analog outputs, with each terminal board handling 10 inputs and 2 outputs. Cables connect the terminal board to the VME rack, where the VAIC processor is housed. The VAIC converts analog inputs to digital signals, transmitting them via the VME backplane to the VCMI board and then to the controller. For outputs, it converts digital signals to analog currents, which are sent through the terminal board to the customer's circuit. VAIC is compatible with both simplex and TMR (Triple Modular Redundant) systems. In a TMR setup, input signals are distributed to three VME racks (R, S, and T), each with its own VAIC board. Output signals are generated by a special circuit combining the currents from all three boards. If one VAIC fails, it is excluded from the process, while the remaining two boards continue to deliver the required output. In a simplex setup, a single VAIC processes the inputs and generates the necessary output currents.
COMPATIBILITY:
There are two generations of the VAIC board, each with corresponding terminal boards. The first generation includes all versions up to and including VAICH1C, with VAICH1B being part of this group. These boards can drive 20 mA outputs with support for up to 500 ohms of load resistance at the end of 1000 feet of 18-gauge wire. For proper functionality, these boards require terminal board TBAIH1B or earlier, and they are also compatible with all versions of DTAI terminal boards.
The latest generation, starting with VAICH1D, is designed to handle higher load resistance for a 20 mA output drive. It provides up to 18 V at the terminal board screw terminals, allowing operation with loads of up to 800 ohms over 1000 feet of 18-gauge wire, with an additional safety margin. This generation requires terminal board TBAIH1C or later, or any version of STAI terminal boards.
OPERATION:
The VAIC board has two generations, each paired with specific terminal boards. The original VAIC generation includes all versions up to and including VAICH1C, which encompasses VAICH1B. These boards can handle 20 mA outputs with up to 500 ohms of load resistance at the end of 1000 feet of 18-gauge wire. For proper operation, this generation requires terminal board TBAIH1B or earlier and is compatible with all revisions of DTAI terminal boards.
The latest generation, starting with VAICH1D, is engineered to support higher load resistance for 20 mA outputs, providing up to 18 V at the terminal board screw terminals. This allows for operation with loads of up to 800 ohms over 1000 feet of 18-gauge wire, with a safety margin. For this generation, terminal board TBAIH1C or later, or any version of STAI, is required.

How many inputs and outputs does the VAIC board support?
The VAIC board supports 20 analog inputs and 4 analog outputs. It connects to terminal boards that handle additional inputs and outputs.
What types of configurations are supported by the VAIC board?
The VAIC board can be used in simplex (single-board) or Triple Modular Redundant (TMR) configurations. In TMR, three VAIC boards work together to ensure fault tolerance and reliability.
What is the maximum load resistance supported by the original VAIC boards?
The original generation VAIC boards support a maximum load resistance of 500 ohms when driving 20 mA outputs over 1000 feet of 18-gauge wire.
How much load resistance can the newest VAIC board support?
The latest VAIC boards, starting from VAICH1D, support up to 800 ohms of load resistance for 20 mA outputs, with up to 18V available at the terminal board screw terminals.
