Electronic relays have evolved a lot since their introduction in the early '30s, but their basic purpose hasn't changed. Transistors and integrated circuits have replaced vacuum tubes and the term ...

“You could’ve done that with a 555 timer.” But what if all you have on hand is an ESP8266? [TechColab] needed to control a solenoid valve with a short pulse via a solid-state relay (SSR) but found ...

Many electronic designs can take advantage of the improved performance of solid-state relays (SSRs) relative to that of electromechanical relays (EMRs) that perform the same circuit function. OptoMOS® ...

Mechanical relays, contactors, and switches control the flow of electricity by the mechanical action of two conducting elements. The physical contact of two conducting elements creates a path for ...

When we think of relays, we tend to think of those big mechanical things that make a satisfying ‘click’ when activated. As nice as they are for relay-based computers, there are times when you don’t ...

Vishay Intertechnology, Inc. introduced the first three devices in its new VOR family of hybrid solid-state relays designed to deliver high reliability and noiseless switching for telecommunications, ...

Solid State Relay (SSR) is a solid-state replacement of electro-mechanical relay, and is commonly used for general purpose switching of signals and low power AC/DC loads. It consists of a ...

Solid-state relays are much smaller than corresponding single-pole relays. They are also faster, dissipate less power, and withstand a larger number of operations. And unlike electromechanical relays, ...

Solid-state relays provide robust solutions for electronic switching in load control applications and hold many advantages over electromechanical relays. New, emerging solid-state relay designs offer ...

VOR1003M4T is an industrial-grade relay with a 1 Form A (single-pole normally-open) contact. On the output side there are back-to-back mosfets allowing ac or dc to be switched. Typical output-side ...
