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 ...

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 ...

Some control applications are too small or simple to use even the smallest PLC, but still need more flexibility than a simple relay. That's why engineers at Schneider Electric, Palatine, Ill.

A single-coil latching relay is a relay with memory, usually with a magnetic structure that provides two stable positions for the armature that holds the movable contacts. A permanent magnet provides ...

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 ...

An experienced protection and integration engineer can help determine the best configurable relay settings to provide maximum system protection and advanced functionality. Photo courtesy: Emerson ...

Programmable logic controllers (PLCs) are used extensively throughout the world. Over time, they have advanced to become more user-friendly, efficient, smaller, and less expensive. Different types of ...
