3.7 Implementation of Automation Circuits
After the initial stage of designing an automation circuit for satisfying specific operations or func-
tionalities for a machine, independently of their size and complexity, the next stage concerns the
implementation of this automation circuit and, in general, the appropriate manufacturing of the
whole automation system. In general, the implementation of the automation circuit cannot be
considered a different task from the implementation of the power circuit. Both circuits are imple-
mented and operate at the same time and inside (in most cases) the same industrial panel or rack.
In Figure 3.30, a representative implementation of the simple automation circuit for a motor of
direct start and with a START-STOP button (such as the one in Figure 3.3) is presented. Such
