SYSTEM AND PROCESS FOR ENERGIZING LOADS THROUGH A CONTROL UNIT

摘要

A system and a process for energizing loads through a control unit, and from a power network, said system comprising: connecting elements (10), each including a processing unit (12) operatively connected to a respective power switch (11) 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 (10); a pair of electrical conductors (21) connected to a power network (2) for energizing the loads and which define an energizing means which is common to the connecting elements (10) and to the control unit (3); and a signal conductor (22) not galvanically insulated from the power network (2) and which is common to the processing units (12) and to the control unit (3), connecting them so as to allow the control unit (3) to instruct, through the processing units (12) and through coded electrical signals, the opening and closing of each respective power switch (11).
