In addition, the positioner is used to convert the reference variable W, i.e., either an analog standard signal (pneumatic 0.2\u20131.0 bar g or electrical 4\u201320 mA) or a digitally transmitted signal (<a href=\"https:\/\/arca-valve.com\/en\/arcapedia\/fieldbus\/\">fieldbus<\/a>; e.g., <a href=\"https:\/\/arca-valve.com\/en\/arcapedia\/profibus\/\">Profibus<\/a> or <a href=\"https:\/\/arca-valve.com\/en\/arcapedia\/foundation-fieldbus\/\">Foundation Fieldbus<\/a> \u2013 FF) into a control variable Y (pressure &amp; volume flow) suitable for the selected actuator using the available auxiliary energy (supply air pressure).
