Industrial Electronics Applications for Programmable Controllers, Instrumentation and Process Control, and Electrical Machines and Motor Controls

Students who enter the job market and become electronics technicians must be prepared to work on industrial electronics in many forms. The job responsibilities for these fields are rapidly changing because electronic devices and circuits have become thoroughly integrated into all aspects of modern industrial control systems during the past ten years. As industries have learned to compete in the global marketplace, the role of technicians has changed to the point where they are expected to work on every aspect of an industrial system from the simplest electrical components, such as fuses and motors, to the most complex, such as electronic boards, motor drives, and programmable controllers. This book is designed for students in two-year technical and community colleges and for students in engineering technology programs and engineering programs at four-year universities. It can be used in courses that cover one semester or one quarter or in a series of courses covering one year or more. The book also provides sufficient depth to be a useful resource after students finish school and are working on the job. Chapters do not have to be read sequentially. Rather, each chapter is self-contained so instructors can select specific chapters that provide material for a specific course. ORGANIZATION OF THE TEXT Individual components and smaller circuits are introduced in the early chapters and larger circuits and complete systems are added along the way, specifically in later chapters. Each chapter is also written to stand alone. This allows teachers to change the order of the sequence of chapters to match their course syllabus. Often chapters in books are linked so that they only make sense when they are read in the order they are presented. With this text the teacher can feel free to change the order of the chapters and the student will still understand everything in each chapter. The first two chapters introduce solid-state devices and logic devices used in industrial electronic circuits. In the third edition, Chapter 3 has been enhanced to provide additional programming applications for programmable controllers. This chapter starts by explaining the basic parts of all programmable controllers and then provides numerous applications that show how instructions are used. It also provides much more information and applications than merely reviewing the instruction set from a typical programmable controller. The Allen-Bradley MicroLogix 1000, SLC500 family, PLC2, and PLCS are used as examples. Additional PLC material that explains how PLCs are used in process control and the operation of PID instructions has been added to Chapter 9. Chapter 4 provides an in-depth study of power devices such as thyristors and power transistors and the types of circuit applications where they are commonly used in industrial electronic circuits. Chapter 5 introduces the triggering devices used to control the power electronic devices, and Chapter 6 provides in-depth coverage of optoelectronic devices an industrial lasers. To supplement the information in these chapters, a complete set of manufacturer's data sheets for each major device discussed in these three chapters is provided the appendix. Chapter 7 provides an in-depth study of power supplies, inverters, and converters that are found in all types of industrial electronic circuits, such as AC and DC motor drives, stepper motor and servomotor drives, and other power control circuits. It explains switch-mode power supplies electronic boards. Chapter 8 provides detailed information about operational amplifiers. Chapter 9 has been enhanced in this new edition to include additional information about PID loops that are found in PLCs. This material provides in-depth study of how PLCs use PID loops for process control. This chapter also provides a PID simulation program that can be operated in a PLCS or SLC500 controller without any hardware or complex process system.Kissell, Thomas E. is the author of 'Industrial Electronics Applications for Programmable Controllers, Instrumentation and Process Control, and Electrical Machines and Motor Controls', published 2002 under ISBN 9780130602411 and ISBN 0130602418.
