Precautions for replacement
The minus current cannot be input.
Analog output voltage to the
A616AD
With A60MXR, equivalent or more
resolution value can be obtained
by setting at the analog inputs,
range of -10 up to 10V/high
resolution mode, and User range
while the analog inputs are used at
the range of -5 up to 5V on
Q64AD-GH.
When using a range of -20 up to
+20mA (with A60MXR), negative
current can not be converted with
Q64AD-GH.
Use conversion devices to convert
into a input range.
A60MXR 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.
