Hopefully, by the end, you will have a pretty good understanding of a relay system. Let’s start by talking about what a relay actually is. According to Merriam-Webster, a relay is, “an electromagnetic device for remote or automatic control that is actuated by variation in conditions of an electric circuit and that operates, in turn, other devices (such as switches) in the same or a different circuit.” In a common relay system, you would push a button to energize a relay, which in turn will pass current through a set of contacts that close when it is energized. There are many common, everyday items that use a relay to operate. We will dive into those in a minute, but first I want to talk about why you may need to use a relay system. A very common reason, especially in an industrial setting, is for voltage and current requirements. Many machines and equipment use a higher voltage to run. To make it safer for the operators, we use a low voltage and current for our controls. You wouldn’t want someone pushing a button with high voltage attached to it. I know I wouldn't want to on a regular basis. It takes a very low amount of current to cause bodily harm. Plus, most push buttons and switches are rated for fairly low current. ========================== Missed our most recent videos?
