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

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.

Peer Relays are a very simple concept: in essence, they allow devices within your Tailnet (so your private, encrypted ...

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 ...

As an electric motor’s rotor turns in close proximity to the motor windings, a bucking voltage or back electromotive force (EMF) is generated. The back EMF (BEMF) generated across the start winding is ...

As automation expands, mechanical functions are relying more and more on electronic control. Solenoids provide an electromechanical interface for many of these applications. In addition, many ...

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 ...
