IO2—1 x AI, 2 x AO Option Card
Description
IO board has 1 analog input that can be configured as voltage
(±10V) or current (0 to 20 mA) and 2 analog outputs that can
be configured as voltage (0 to 10V) or current (0 to 20 mA).
DIP switches on the option card are used to configure along
with parameter settings.
