Since the mid-1980s, semiconductor technology has promised to provide smart power products for solid-state relays that could carry high current and provide unique functions for customers. However, ...

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 ...

Relays usually are driven using optocouplers, which offer isolation between analog and digital grounds to ensure that switching currents in the relay coils do not affect the noise margin of the ...

Impulse relay is a viable alternative for lighting control from multiple locations. In modernistic houses and apartments, lighting schemes to control lights from two or more locations are becoming ...

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 ...
