As an emerging discipline in the field of electrical information, electrical automation is closely related to people's daily living activities and industrial production. In the production work, through the use of electrical automation design can effectively improve work efficiency, save operating costs, effectively play the role of labor.
In order to learn and apply the electrical automatic control system more graphically and intuitively, this paper organizes 28 examples of electrical automatic control circuit diagrams for reference.
