Abstract
Abstract An electronic control and regulation device for a machine or like apparatus has a plurality of printed circuit boards in a housing, each of the printed circuit boards having interconnected analog and digital circuitry with respective analog and digital terminals. The analog and digital terminals of all of the boards are interconnected respectively by analog and digital conductor bundles, the analog conductor bundle running to the machine or apparatus to be controlled, and serving as well to supply the electric current to the analog part of each printed circuit board.
