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 ...

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 ...

Finding a 480V-ac solid-state timer having zero-crossover switching may prove to be an impossible task. Most solid-state timers are rated at only 1A and have voltage ratings no higher than 240V ac.

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, ...

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 ...

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 ...

[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 ...
