The RS D8-I and RS D-U D/A converters are used to convert digital signals to analogue signals.
They are used for converting 8-bit digital signals into analogue current or voltage signals. All modules are equipped with a hold function i.e. the instantaneous output value remains constant even when the input values change.
You can find additional information describing the input/output characteristics of the A/D converters on our web site at http://www.weidmueller.com/54103/Downloads/Printmedien/Handbuecher/Beipackzettel/cw_index.aspx
