Equipped with two release current paths and one signal current path, the PSR safety relays are designed with reinforced insulation between each path and are stated to be protective for all ...

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.

What is a relay? What is zero voltage switching? How to create a zero-crossing relay driver with a simple external circuit. A relay is a device that allows for a smaller electronic switch to control a ...

Factory equipment continues to become increasingly intelligent in large part due to the improved processing power and communication abilities found within underlying controllers, sensors, and ...

Safety is a major concern in a good many motor-driven applications. This is true in industrial applications where motion starts when power is applied and especially true when power is restored after ...

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 ...

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 ...
