The electrical connections of the subassembly are led spatially and electrically separately from the mechanical attachment of the subassembly to the card rack. The subassembly can be an additional component mounted on the card rack with a new additional function, so that the controller can be flexibly adapted to a given requirement profile in a simple manner by combining, in a flexible manner, a plurality of subassemblies with different layouts and modes of operation on the card rack.
