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 ...

The Jokab Safety Sentry family of safety relays from ABB simplify troubleshooting and resetting to reduce downtime, are universal for all common applications to reduce stock, and are easily wired and ...

When it comes to electronics, it seems like a relay is such a simple device – yet, it is able to interface some pretty elaborate high-end systems with a fire alarm system. Working with relays is an ...

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 ...

IDEC Corporation announces the release of its new HR5S safety relay module. This latest addition to IDEC’s family of safety devices gives designers and OEMs more options to provide better end user ...

In this Design Idea, we look at how electromechanical relays display hysteresis behavior that is surprisingly similar to the solid-state Schmitt trigger circuits, and how they can be used for many ...

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.
