This chapter covers representative general-purpose relays used in the control circuits of most industrial, commercial, and consumer products. Relay names and terminology are in accordance with ...

When voltage sags occur inside or outside of a facility, properly placed power quality mitigation technology will save sensitive equipment from costly shutdowns. The cost of this mitigation equipment ...

Relays and contactors use a variety of technologies to switch signals and power connections. Many devices called relays use similar techniques and topologies, but the terminology can be confusing.

Over the years, control relays of various types have been used by the hundreds — even thousands — to control nearly every function in commercial and industrial processes. Today, many of those ...

Global revenue in the aircraft relay and contactor market has declined by more than 20 percent as a result of the ongoing Covid-19 pandemic. The market decline is expected to stabilize in 2021, ...

If you've ever wondered how electronic devices manage to control circuits with precision and safety, you're thinking about the magic of relays. Relays act as the unsung heroes in many of our devices, ...

Electromagnetic contactors and relays serve as fundamental components in modern electrical systems, providing reliable switching mechanisms in applications ranging from power distribution to ...

Last column, I wrote about various applications where fire alarm relays could be used to integrate a commercial fire alarm system with other electrical systems at a customer’s site to provide them ...

Sometimes, the most unexpected detours lead to the most interesting discoveries. After a brief break, I found myself revisiting latching relays—not just as components, but as puzzles waiting to be ...
