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 ...

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 ...

Solid-state relays (SSRs) control load currents through solid-state switches such as triacs, SCRs, or power transistors. Solid-state relays (SSRs) control load currents through solid-state switches ...

Modern relay technology has been around since the 1960s, and its main function is to provide automation with electrical isolation for many applications. All relays have two separate circuitries: input ...

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 ...

With a few mouse clicks you can easily purchase Solid State Relays (SSRs) online. Or you can make one at home with a handful of different electronic parts. The question is– should I buy it or make it ...

If you've ever wondered how electronic devices manage to control circuits with precision and safety, you're thinking about the magic of relays. Relays act as the unsung heroes in many of our devices, ...

The proper selection of 3-phase solid state relays for motor control application depends not only upon a comprehensive understanding of 3-phase SSRs, but also of the 3-phase power system and typical ...

Even though the function of single phase and three phase relays are quite similar, their applications can vary significantly. This is primarily due to the characteristics of three phase power circuits ...

[SaltyPuglord] needed a solid state relay for a project. We’d have just bought one, but he decided to design his own in LTSpice. Along the way he made the video below, which is pretty informative and ...

“This milestone marks a first for the MEMS industry with the demonstrated switching and control of 0.5 megawatt of power. It ...

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 ...
