《Learn Sequence Control Easily with Cartoons》, which shows the actual automatic control process in cartoon form.

In modern society, devices using automatic control are widely used in all fields.
Automatic control circuits are built into not only home appliances that we use frequently, such as washing machines and air conditioners, but also elevators in buildings and traffic lights at intersections, making our lives more comfortable and convenient.


Among the automatic control methods, sequence control used in traffic lights and elevators is the most basic method. If you are learning about sequence control for the first time, it is recommended to start with control by electronic relay.
Also, to understand the operation of sequence control, it is a good idea to look at the sequence diagram and actually imagine the sequence operation.

Taking these points into account, this book has the main character, Kim Myeong-seok, actually wiring a basic sequence circuit using an electronic relay.
It shows the wiring divided into three stages and explains it in detail so that you can imagine the actual operation of the sequence diagram.
Additionally, when drawing a wiring scene, you can get a realistic feel for the wiring method by drawing an actual circuit using real electronic relays, etc. from the production company.
