Here’s a really fascinating circuit that implements a combination lock using relays and logic gates. Even with the schematic and written explanation of how it works we’re still left somewhat in the ...

Most industrial facilities include electric motors that require overload relays for protection, control and monitoring purposes. The latest overload relays are often called motor management relays ...

If you’re at all familiar with digital computing, you’ll know that computers represent everything in binary values of one and zero. Except that’s not technically the only way to do computing! You can ...

Long before tubes and semiconductors became the main active components in digital circuitry, relays were used for highly sophisticated control of electronic systems. Today’s retro-engineering and ...

This article presents some application ideas of relays and provides simple solution in current and voltage switching applications. Typical designs using relays also described in this document. n this ...

You can find these devices in discrete and process industries, on the plant floor in the manufacturing environment and even in commercial and consumer applications such as gate controls, vending ...
