Description
Digital and analog channelsSelectable current and voltage for AI and AOCounter 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.
