FUNCTIONAL DESCRIPTION:

IS200VAICH1CBA 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 Analog Input/Output (VAIC) board accepts 20 analog inputs and controls 4 analog outputs. Each terminal board accepts 10 inputs and 2 outputs. Cables connect the terminal board to the VME rack where the VAIC processor board is located. VAIC converts the inputs to digital values and transfers them over the VME backplane to the VCMI board, and then to the controller. For outputs, the VAIC converts digital values to analog currents and drives these through the terminal board into the customer circuit. VAIC supports both simplex and triple modular redundant (TMR) applications. When used in a TMR configuration, input signals on the terminal board are fanned out to three VME board racks R, S, and T, each containing a VAIC. Output signals are driven with a proprietary circuit that creates the desired current using all three VAICs. In the event of a hardware failure, the bad VAIC is removed from the output and the remaining two boards continue to produce the correct current. When used in a simplex configuration, the terminal board provides input signals to a single VAIC, which provides all of the current for outputs.

COMPATIBILITY:

There are two generations of the VAIC board with corresponding terminal boards. The original VAIC includes all versions before and including VAICH1C. VAICH1B is included in this generation. When driving 20 mA outputs these boards support up to 500 load resistance at the end of 1000 ft of 18 wire. This generation of the board requires terminal board TBAIH1B or earlier for proper operation. They also work properly with all revisions of DTAI terminal boards. The newest VAICH1D and any subsequent releases are designed to support higher load resistance for 20 mA outputs drive voltage: up to 18 V is available at the terminal board screw terminals. This permits operation into loads of 800 with 1000 ft of 18 wire with a margin. This generation of the board requires TBAIH1C or later, or any revision of STAI.
