Optional analog inputs (AI)
When plugged into one of the optional card slots on the card cage, the ROC800 AI-16 card
provides four additional analog inputs.
The AI channels are scalable, but are typically used to measure either a 4-20 mA analog
signal or a 1-5 Vdc signal. If required, the low end of the AI module's analog signal can be
calibrated to zero. For more information, see
