*4: AG is the GND terminal of the analog circuit. Connecting it to the
GND terminal of an external device is not mandatory, but a higher
level of accuracy may be obtained when it is connected.
If there are three or more channels of the input range of -10 to 10V
and the external devices connected to the channels shares a
common line, the AG terminal must be connected the shared
common line of the external device.
(See the figure below.)
POINT
When the current input is selected, do not connect the sink type output
device and the source output device together. If this happens, normal
A/D conversion value cannot be stored.
