Abstract

An automating assembly for electrical installations comprises a plurality of input and output modules each detachably fastened to a respective modular module carrier removably attached to a support bar. The module carriers each include an integrated circuit connectable to the integrated circuits of adjacent module carriers by means of rigidly mounted plug strips and cooperating jack strips connected to the integrated circuits of the module carriers via flat flexible cables. Each modular module carrier is connected to a respective terminal block for the coupling of external wires to the automating assembly. The module carriers are designed to facilitate the removal of individual module carriers for applications in which a reduced number of input and output modules is required.
