1. A controller for an industrial automation system, comprising a main module including:
(a) a housing having a base and a cover detachable from the base, said base having a recess configured for connection with a mounting rail;
(b) a backplane bus printed circuit board arranged within said housing and connected with said base, said backplane bus printed circuit board oriented in a plane parallel to an extending direction of said recess, said backplane bus printed circuit board providing a backplane bus;
(c) a main printed circuit board arranged within said housing and connected with said backplane bus printed circuit board, said main printed circuit board oriented perpendicularly to said backplane bus printed circuit board;
(d) a heat sink arranged in said housing and mounted on said base, said heat sink having a first side facing said backplane bus printed circuit board and a second side facing said main printed circuit board for cooling circuit board components of said main printed circuit board; and
(e) a plug connector coupled with said backplane bus of said backplane bus printed circuit board and configured for connection with at least one laterally stackable expansion module.
