February 24, 2015 - Phoenix Contact introduces PLC Logic relay system that combines basic programmable logic capability with the company’s PLC relays, creating a “smart” relay system. The PLC Logic ...

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.

Abstract: Users of protective relays apply these devices specific to their needs and applications. In order to perform this task, schemes are developed and applied to protective relays in the form of ...

Ladder logic uses switch or relay contacts to implement Boolean expressions. In years past, ladder logic was made possible with discrete relays and was sometimes termed “relay logic.” Today most ...

When a PLC is used primarily to replace relays, timers, and counters, it's hard to beat the simplicity and usefulness of ladder diagram programming. Their ability to accept programming in ladder ...

Definition – What is a PLC? A programmable logic controller is a computer device used by industrial control systems. They can be used wherever there is a need for control devices, due to the fact that ...

If your usual tools are the Arduino and the Raspberry Pi, you might find it surprising that the industrial world tends to run on Programmable Logic Controllers, or PLCs. You can think of a PLC as a ...

There are a few words in the electrical engineering lexicon that will perk any hardware hacker’s ears. The first of course is “Nixie tubes” with their warm cold war era ambiance and nostalgia inducing ...
