Features: This book takes an applied perspective to introduce the design methods of relay-contactor control systems, programmable logic controller (PLC) systems, and electrical control systems. The book is divided into two main parts. The first part includes common low-voltage electrical appliances, basic elements of relay-contactor control circuits, and analysis of electrical control circuits for typical equipment. The second part takes the Siemens S7 series PLC as an example to introduce the structure, principle, instruction system, editing methods, and system design methods of PLCs. Starting from the S7-200 series to the technologically advanced and maturely applied S7-300/400 series PLCs, the content is presented in a gradual and progressive manner. To assist students in understanding, each chapter includes an appropriate number of examples and exercises. This book can serve as a textbook for automation and electromechanical majors in vocational and technical colleges and can also be used as a reference for engineering technicians.
