Block diagram
The block diagram represents the simplified circuit. Only the essential parts are taken into consideration. The devices are copied by means of rectangles or squares and properly marked.
Figure
Terminal diagram
The terminal diagram represents the electrical connection between the devices. Thus it allows the exchange of products, devices and parts of devices. The components are represented with the corresponding lines, junctions and terminal designations.
Figure
Circuit diagram
The circuit diagram is the detailed representation of a circuit. It represent the operating method of an electrical system or of single devices. The devices are drawn in their basic setting and in dead condition.
