This survey of modern industrial electronics provides a comprehensive treatment of devices, theory, circuits and applications. It is designed for technology program students who have completed a traditional dc and ac circuits course, as well as having a basic knowledge of algebra and trigonometry. Topics covered include programmable logic controllers; process control; servomechanisms and microprocessors. The discussions, which include practical material such as trouble-shooting, are oriented towards real industrial situations. End-of-section and end-of-chapter review questions allow students to verify their comprehension. Some chapters also contain appropriate optional lab exercises.
