‘Relay’ detailed information on relays

By Control Engineering Staff January 26, 2006
“Electrical Relays: Principles and Applications” claims to be the first illustrated encyclopedia of relays.

Types of relays include ordinary electromagnetic, reed switch, solid-state, thermal and high-voltage devices as well as current, frequency, differential, distance and microprocessor-based relays. If you need descriptions of each, principles of operation, and applications for all basic types, consider the “the first illustrated encyclopedia of electrical relays,” according to the publisher, “ Electrical Relays: Principles and Applications ,” by V. Gurevich, a CRC Press Book (Taylor & Francis Group), 2005, hard cover, 671 pages, $149.

Also offered is historical background on designs, principles of operation of relay components (vacuum, gas discharge, and semiconductor devices), more than 1,200 illustrations, “easy-to-understand language, without mathematical treatment,” publisher says.

Recent Control Engineering coverage on relays includes:

Overall vibration modules reduce unplanned downtime

Safety logic advances with relay, PLC
