Abstract
An apparatus for process automation for use in an area where there is a risk of explosion and in which dusts may occur, including a wall structure serving as a housing of the apparatus and having a first wall structure section defining a first housing inner area and a second wall structure section defining a second housing inner area separated from the first housing inner area, wherein a first circuit arrangement is arranged in the first housing inner area and the first housing inner area is dust-tightly enclosed by the first wall structure section so that the dusts cannot penetrate into the first housing inner area and the explosion safety of the first housing inner area is ensured by the dust-tight enclosure, one or more electrical circuits being arranged in the second housing inner area and all the electrical circuits arranged in the second inner area forming an altogether intrinsically safe second circuit arrangement.
