The voltage/current cannot be
mixed for one module.
A616AD can set the data
format to [-2048 to 2047].
However, Q68ADV/I cannot
set. When using the
conversion data of Q68ADV/I
in [-2048 to 2047], convert with
sequence program.
When using A616AD in [-5 to +
5V] range, Q68ADV can obtain
equivalent resolution or more
than A616AD by setting in [-10
to 10V] range/high resolution
mode or user range.
When using A616AD in [-20 to
+20mA] range, use Q68ADI in
user range.
A616AD is the accuracy in
respect to the full scale, and
Q68ADV/I is the accuracy in
respect to maximum digital
output value.
