Newly revised, this book offers the logic of design to
startup, operation and maintenance, and all aspects of wiring,
relay logic, programmable logic controllers, and a host of
electrical control applications and challenges you'll
encounter on the job.
A new chapter covers
heat and enclosures including information on the creation of
heat in electronic devices and how it can be dissipated.
Beginning with the
basic principles of electrical logic, the author guides you
through each step in the design of a sequencing logic system,
including developing the schematic diagram, making a bill of
material, and designing component wiring diagram.
You will learn the
fundamentals of programmable logic controls (PLC's), including
number in systems, basic memory structure, system addressing
and the common instruction set.
takes you step by step through solving problems that require
bailing circuits, sorting systems, and counting the relays,
including encoding and decoding.
The contrast between
digital and analog control systems is also fully examined.
Case histories illustrate the principles covered. as well
specific troubleshooting techniques.
