Compatibility Precautions for replacement
The conversion speed of Q68ADV/I to
A68AD-S2 has become quick. And
then, on A68AD-S2, the noise that did
not import on Q68ADV/I can be
imported as analog signal. In this
case, use the averaging processing
function to remove the effect of noise.
I/O occupied points has changed to
16 points.

The recalculation of internal current
consumption [5VDC] is required.
