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 ...

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 ...

Hybrid relays are changing the way we think about switching inside electronic circuits. By combining the fast response of solid-state components with the reliability of mechanical contacts, these ...
