Analog signals must be within the
10V common mode voltage range
which is referenced to the analog
input common (GND). Typically, this
is accomplished by connecting to
user ground. If an input channel
floats outside of this range, invalid
input readings will result.
Current Input
Output ATTENTION: The 249 ohm
input current shunt is rated
at 0.25 Watts. Do not
exceed this rating.
