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 simple and convenient way to interface 2 relays for switching application in your project. This relay driver boosts the input impedance with a regular BC547 NPN transistor (or equivalent). Very ...

Equipped with two release-current paths and one signal-current path and with reinforced insulation separating the paths, the PSR safety relays are said to provide reliable protection for any and all ...

What is a relay? What is zero voltage switching? How to create a zero-crossing relay driver with a simple external circuit. A relay is a device that allows for a smaller electronic switch to control a ...

Relays and contactors use a variety of technologies to switch signals and power connections. Many devices called relays use similar techniques and topologies, but the terminology can be confusing.
