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 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, ...

The series 605-210 high-voltage dc solid-state relay, about the size of half a hockey puck, offers high-power switching capability with a 10-A 270-V dc rating. Commercial off-the-shelf (COTS) ...

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 ...

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 ...

This application note presents different types of overvoltage protection devices for solid-state relays. The document also provides suggested recommendations on their selection and use with the Vishay ...
