[Alex] was tasked with a control design problem for a set of motors. The application called for the back of a truck to open up, some 3D scanning equipment to rise from its enclosure, and finally 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 ...

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 ...

This file type includes high resolution graphics and schematics when applicable. According to the research firm IHS Inc., about 54 million relays and timers were purchased in 2013, a number projected ...

This looks like one of those projects that started out as a glimmer of an idea and led down a rabbit hole. But it’s a pretty cool rabbit hole that leads to homebrew neon seven-segment displays on a ...

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 ...

Designed to interface PC or PLC logic to machines, the Releco Interfacer universal relays pack both ac and dc circuits in the same unit and include a built-in surge supressor. Dedicated ac or dc units ...

Large scale digital logic began not with the vacuum tube but the electromechanical relay. Although vacuum tubes were available at the time – and were used on competing machines – Konrad Zuse chose to ...

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 ...
