Abstract
A system and a process for energizing loads through a control unit, said loads being energized from a power network, said system comprising: connecting elements, each including a processing unit operatively connected to a respective power switch so as to lead the latter to opening and closing conditions, de-energizing and energizing a respective adjacent load that is electrically coupled to the connecting element; a pair of electrical conductors connected to a power network for energizing the loads and which are disposed so as to define an energizing means which is common to the connecting elements and to the control unit; and a signal conductor not galvanically isolated from the power network and which is common to the processing units and to the control unit, connecting them so as to allow the control unit to instruct, through the processing units and through coded electrical signals, the opening and closing of each respective power switch.
