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 has ...

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 ...

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 ...

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 ...

A new solid-state relay with a 0.5 mA trigger current and high isolation is designed for dense, low-noise systems across security, industrial, medical, and EV-charging applications.

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, ...

“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 ...

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 ...

Evolving from magnetic coil actuators to capacitive-coupled isolation, the ever-shrinking relay continues to be an essential component within the automation arena. Modern relay technology has been ...

Celduc relais single-phase solid-state relays, delivering silent, precise, and durable control for railway heating and ...

Weidmuller introduces the new TERMOPTO solid-state family of relays- electrical isolation in the size of a terminal block. The innovative TERMOPTO functions as both a terminal block for signal ...

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 ...
