If you’re at all familiar with digital computing, you’ll know that computers represent everything in binary values of one and ...

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.

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 ...

We are fascinated when we see machines work together, seemingly with minds of their own. The TV show “How It’s Made” became popular for simply showing how products are made in an automated factory ...

The new SIRIUS 3RK3 modular safety system (MSS) from Siemens Energy & Automation, Inc. is the ideal solution for applications that require the simplicity of safety relays and the added functionality ...

The objective of protective relays and protective schemes is to protect electrical equipment such as transformers, lines, cables, bus bars, etc. during abnormal system conditions. Hence, protective ...

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 ...

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 ...
