Precautions for replacement
The minus current cannot be input.
Analog output voltage to the
A616AD
When using a range of -5 up to +5
(with A60MX), With Q64AD-GH,
equivalent or more resolution value
can be obtained by setting at a
range of -10 up to 10V/high
resolution mode, or user range.
When using a range of -20 up to
+20mA (with A60MX), negative
current can not be converted with
Q64AD-GH.
Use conversion devices to convert
into a input range.
A60MXRN is the accuracy in
respect to the full scale, and
Q64AD-GH is the accuracy in
respect to maximum digital output
value.
Consider replacement with
multiple Q64AD-GH.
Q64AD-GH cannot set to 0 point
with I/O assignment.
Wiring change is required.
The recalculation of internal
current consumption [5VDC] is
required.
