Fundamentals of Electrical Control

From the logic of design to startup, operation & maintenance, this "user friendly" reference covers all aspects of wiring, relay logic, programmable logic controllers, & a host of electrical control applications & challenges you'll encounter on the job. Beginning with the basic principles of electrical logic, the author proceeds to guide the reader through each step of the design of a sequencing logic system, including developing the schematic diagram, making a bill of materials, & designing component wiring diagrams. You'll learn the fundamentals of programmable logic controllers (PLCs), including numbering systems, basic memory structure, system addressing, & the common instruction set. The easy-to-follow presentation takes you step by step through solving problems that require bailing circuits, sorting systems, & counting with relays, including encoding & decoding. The contrast between digital & analog control systems is also fully examined. Case histories complete with schematics & wiring diagrams are used to illustrate the principles covered, as well as to demonstrate specific troubleshooting techniques & experiences.Phipps, Clarence A. is the author of 'Fundamentals of Electrical Control' with ISBN 9780881732177 and ISBN 0881732176.
