Digital and analog channels Selectable current and voltage for AI and AO Counter functions The module is a universal mixed module.
On this module, digital I/O and analog I/O are combined.
A current or voltage signal can be used for the analog I/O as desired.
Counter functions on two of the digital inputs expand the range of use.
