Features: This book starts with the working principles and application methods of common low-voltage electrical appliances in electrical control, introduces the basic knowledge of electrical diagrams, systematically explains the basic control principles and basic control circuits of conventional electrical control circuits, and provides a detailed analysis of the electrical control circuits of several typical production machinery. Combined with examples, it introduces the design methods of electrical control circuits and briefly covers the relevant knowledge of electrical design and CAD. Based on the introduction of the working principles of Programmable Logic Controllers (PLCs), it elaborates in detail on the hardware structure, working principles, instruction system, and applications of the FX2N series PLCs from Mitsubishi Electric Company of Japan. It also briefly introduces the hardware configuration, programming, and configuration of the S7-200 series PLCs from Siemens AG of Germany. After introducing the design principles and content of PLC electrical control systems, it presents several practical application examples of PLC electrical control technology. Additionally, to highlight the practical teaching aspects of this course, it provides detailed introductions to the methods and content of PLC electrical control technology, along with several course design topics. The book also covers the content of comprehensive experiments related to this course and offers suggestions for conducting PLC electrical control design-based comprehensive experiments. The features of this book are: adhering to the teaching principle of closely integrating professional technical courses with engineering applications, and clearly structuring a complete system of electrical control technology from conventional relay-contactor control to microcomputer-based PLC control. The content is carefully selected, progressive, easy to understand, practical, and application-focused. The explanations are concise, illustrated, and easy to comprehend, making it suitable for teaching and self-study. This book can serve as a textbook for electrical control and programmable controllers-related courses in electrical and mechanical-electrical disciplines at universities and colleges, and can also be used as a reference book or training manual for relevant technical personnel in the mechanical-electrical industry.
