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 ...

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 ...

[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 ...

A Programmable Logic Controller, commonly known as a PLC, is a robust industrial computer designed to control manufacturing processes and machinery. Initially developed to replace relay logic systems, ...

The PuffinPLC Project is an effort to produce a Linux-based GNU Public Licensed Programmable Logic Controller (PLC). PLCs were developed in the 1960s to replace the complex electrical relay circuits ...

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 ...

This Design Idea shows how to use a 63¢ (Q=1) microprocessor reset voltage detector IC in a relay coil drive circuit to greatly reduce the coil’s hold-in current. When asked to estimate the coil ...

In electronic and industrial automation systems, relay modules play a crucial role by allowing low-power control signals to switch high-power devices. Selecting between a 5V relay module and a 12V ...

Safety is a major concern in a good many motor-driven applications. This is true in industrial applications where motion starts when power is applied and especially true when power is restored after ...
