The voltage/current cannot be
mixed for one module.

16-bit signed binary
(Normal resolution mode: -4096 to 4095,
High resolution mode: -12288 to 12287, -16384 to 16383)
As concept of gain value is
changed, refer to [Analog-
Digital Converter Module
User’s Manual] and then,
confirm the I/O characteristics.
80µs/channel
(When there is temperature drift compensation, the time calculated by adding 160 µs will be
used regardless of the number of channels used.)
The conversion speed of
Q68ADV/I to A68AD has
become quick. And then, on
A68AD, 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.
