General Description
The 1746-FIO4I and 1746-FIO4V fast analog I/O modules provide two
input and two output channels. Input channels are the same for both
types of modules: you select either current or voltage operation for
each channel. The 1746-FIO4I module contains two current-output
channels, while the 1746-FIO4V module contains two voltage-output
channels.
