From the logic of design to startup, operation and maintenance, this reference covers all aspects of wiring, relay logic, programmable logic controllers, and a host of electrical control applications and challenges you'll encounter on the job. Beginning with the basic principles of electrical logic, the author guides you through each step of the design of a sequencing logic system, including developing the schematic diagram, making a bill of materials, and designing component wiring diagrams. You'll learn the fundamentals of programmable logic controllers, including numbering systems, basic memory structure, system addressing, and the common instruction set. The presentation takes you through solving problems that require bailing circuits, sorting systems, and counting with relays, including encoding and decoding.This construction requires careful planning to match the schematic wiring diagram to actual relay construction. ... they should be on the same relay, because relay coils operating in parallel may have a slight difference in their time -constant.
