One advantage of solid-state relay (SSR) over conventional electro-magnetic relay (EMR) is its tear and wear free operation. S201S01 from Sharp is a good example. Here is the circuit diagram of a DIY ...

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.

Most solid-state timers are rated at only 1A and have voltage ratings no higher than 240V ac. Solid-state relays (SSRs), in contrast, have much higher ratings and are readily available. The universal ...

[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 informa… ...

Another type of SSR, called a ‘random turn on’ solid state relay, is used to implement dimming. It works the same way as a normal SSR, except that there is no zero-crossing detection circuit.

Littelfuse, Inc. introduced the CPC2501M, a robust, self-actuating, normally closed solid-state relay optimized for chime ...

Since the introduction of solid-state relays some decades ago, the debate over which is better, solid-state relays (SSRs) or electromechanical relays (EMRs), has gone on. The ...

Two main types of these relays exist: electromechanical relays (EMRs) and solid-state relays (SSRs). EMRs have been the tried and ready solution for managing load circuits.

Imagine a 60-Hz ac power circuit. A mechanical relay, ... Solid-state triac devices may be used to interrupt the flow of electricity in a manner that is synchronous with the ac current waveform.
