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 ...

A time delay relay controls the timing of electrical circuits by delaying switching operations. Commonly used in HVAC systems and motor control, it enhances safety, prevents equipment damage, and ...

What's a designer to do when challenged with a switching application that requires handling up to 70 kV? These applications are not as rare as one may think. In fact, a broad range of applications in ...

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 ...

Hybrid relays combine a mechanical switch with a solid-state switch, and they are set up in parallel to control a single load ...

In a not yet dim past we started this series with an ‘energy-efficient relay’. Here is a variation on that topic, and a super-simple one at that. The big disadvantage of the energy-efficient relay ...

[Glitch] got his hands on a slew of relays which are meant for use in industrial equipment. They are designed to operate at 24V. He wanted to use these with common microcontrollers and instead of ...

Abstract: PRACTICALLY all of the telephone switching equipment in an exchange is made up of wired assemblies - assemblies of relays and other components interconnected by a multiplicity of wires.
