Comprehensive coverage of relay controls, which Alerich describes as the backbone of the industry.
The text moves from simple equipment to complex industrial systems, focusing on both theoretical and hands-on application:
: Extensive use of schematic/ladder and wiring diagrams to teach students how to interpret and draw control circuits.
: Websites like the Internet Archive (archive.org) often have a wide collection of books, including textbooks. You might find the book you're looking for there.
Over the decades, Alerich partnered with co-author Stephen L. Herman to modernize the text, moving away from pure relay logic to reflect the digital automation used in modern factories. 🎯 Target Audience
: Includes a dedicated unit on VFDs for modern speed and torque control. Programmable Logic Controllers (PLCs)
