Features: This book is divided into three main parts: The first part covers low-voltage electrical components, including the principles of contact operation and failure, relay working principles, and an introduction to various general low-voltage electrical devices; the second part discusses low-voltage electrical circuits, including reading and drawing electrical diagrams, with a focus on the identification and design methods of low-voltage control circuits; the third part focuses on Programmable Logic Controllers (PLCs), specifically introducing the parameter selection, wiring methods, and programming techniques for the FX series PLCs. This book emphasizes fundamental concepts, presents up-to-date and simplified content, and closely integrates theory with practice. Compared to similar textbooks, it strengthens the logical connections between content to facilitate teaching and learning for instructors and students. To enhance students' ability to troubleshoot low-voltage circuit faults, it adds a section on "Contact and Relay Principles." To improve students' ability to identify and design circuits, it introduces specialized methods for handling sequential circuits, such as the "Trial Method" and "Matrix Method." This book serves as a textbook for industrial automation, mechatronics, and mechanical design and manufacturing majors in ordinary universities, as well as a reference for other related disciplines.
