or MOSFET that switches the mains power using the output from the optocoupler. Finally, there is usually (but not always) a ‘zero-crossing detection circuit’. This causes the relay to wait ...

An optocoupler relay, also known as an opto-isolator relay, is a device that combines the functionalities of an optocoupler and a relay to provide electrical isolation between input and output signals ...

As [Mic] often got requests to make high-power switching boards, he recently finally gave in and designed the one shown above based around a solid-state relay. Some of our readers that already ...

All of the surface mount (SMD) components come pre-soldered. You simply need to add the relay, optocoupler (optional), IC, voltage regulator, and capacitor. Mount a normally-open, momentary SPST ...

Japanese electronics manufacturer Toshiba has released a new PV output photocoupler for solid-state relay. The TLX9910 solution is made for automotive equipment, such as battery management systems ...
