A module is proposed for a control system comprising several modules juxtaposed on a carrier, particularly an analog input/output module for receiving inputs and/or outputs. The circuit parts common to all the inputs and/or outputs are located on circuit board, whilst the specific circuit for each input and/or output is in each case provided on a separate circuit board. The circuit boards are received in sliding blocks, which can be inserted in the module casing from the front. For this purpose the casing contains several superimposed guides. The electrical connection is formed when the sliding blocks are inserted by means of plug connections which are located on the circuit board with the common circuit and the circuit boards with the specific circuits.

A modular system for electronic controls comprising: a rack having a generally planar face, and a plurality of guides arranged generally perpendicular to the face and extending rearwardly from the face; a plurality of enclosures, each enclosure engaging at least one of the plurality of guides, each enclosure containing at least one circuit board, each enclosure comprising: an upper portion and a lower portion, the at least one circuit board being situated therebetween in a slit defined by confronting surfaces of the upper and lower portions, a front edge of the slit providing access to the circuit board to provide a plug connection thereto, a front face defines by the upper and lower portions including retaining means for retaining a plug in connection with the circuit board, and shoulders for engaging the generally planar face of the rack, and a grip projecting forwardly from one side of the front face for aiding in the insertion and removal of the enclosure with respect to the rack; and a cover pivotally connected to the rack for movement between an open position permitting replacement of the circuit board containing enclosures, and a closed position preventing the replacement of the enclosures.
