— Overvoltage protection

— Automation system and BMS

The boundary between traditional systems and automation systems can be identified in the ability to communicate that devices developed for automation systems have natively and that, on the contrary, is not usually provided for in traditional devices:

— Classes of applications of an automation system

Class 1

Lighting, heating, ventilation, air conditioning, actuators Rescue, anti-intrusion, gas leakage, fire, flooding, technicians

Controls

in traditional low-voltage electrical systems the control device acts directly on the power circuit of the controlled consumer.

Alarms

Sound diffusion

Control Class 2

Sound diffusion Communication

Talking car

Telephone, intercom Class 3 Video Communication

in automation systems the control circuit is separated from the power circuit. The former consists of a signal network through which the control and actuation devices, equipped with their own processing and communication electronics, are able to exchange information in the form of digitally encoded messages. To the power circuit are connected the utilities that need the network voltage to operate. The applications that can be realized with an automation system do not differ only theoretically from those that can be realized with a traditional system, but in practice, as soon as more articulated logics are realized, for example, than a simple inverted one, the wiring complexity of a traditional system increases exponentially to the point of making its realization impracticable. The applications that can be realized with an automation system can be classified as shown in the table. Those of interest for energy saving are practically all in the following class 1.
