Frequently Asked Questions (FAQ)

• What does VAIC stand for? It is the functional acronym for VME Analog Input Card.
• What sensors does it support? It has built-in libraries for linearizing RTDs (Resistance Temperature Detectors) and thermocouples, among other analog signals.
• Can it be used in a TMR system? Yes, but you must ensure you procure the specific board version manufactured for TMR (Triple Modular Redundant) or Simplex use.
• What are the TBAI boards? Terminal Board Analog Input (TBAI) boards are the field wiring interfaces that connect to this VAIC processor card.
• What do the three LEDs indicate? They provide visual status for board operation (RUN), fault conditions (FAIL), and general status updates.
• What is the advantage of 32-bit floating point? It provides very high resolution and wide dynamic range for accurate measurement of analog signals.
• What is the "D" revision? It indicates this is a later revision of the original IS200VAICH1 board, potentially incorporating design improvements or fixes.
