The Guide to Solid State and Electromechanical Relays
The relay is one of the world’s oldest electrical components. Industrial engineers must understand how to identify, control, and troubleshoot all kinds of electrical relays.
Electrical control systems rely on solid-state and mechanical relay devices to manage the logical flow of operations and to amplify power from the control to the load circuit. During design and operation, relays must be thoroughly understood in order to bring about the best results, both for the reliability and the longevity of the machine. In this ebook, learn how to identify various types of relays, read the terminal numbers to understand wiring, and discern between the risks and benefits of choosing certain relays for mission-critical applications.
