Compatibility Precautions for replacement
The conversion speed of Q68ADV/I to
A68ADN has become quick. And
then, on Q68ADV/I, the noise that did
not import on A68ADN 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.

× Wiring change is required.

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