Opto isolated switch
WebJan 15, 2014 · A typical optically isolated relay requires 10 to 20 times less power than an equivalent electromechanical relay. For example, a 5 mA optically isolated relay can often do the same job as an electromechanical relay that requires anywhere from 50 to 100 mA, depending on the electromagnetic force needed to close the coil.

WebOct 11, 2024 · DC solid state relays are usually made with MOSFETs (and an opto-isolator). AC solid state relays are usually made with TRIACs (and an opto-isolator). A TRIAC latches-on until current falls to zero (i.e. the AC zero-crossing) so they are not usable with DC. Unlike regular electro-mechanical relays, AC & DC solid state relays (usually) aren't ... fish restaurant in san franciscoAn opto-isolator (also called an optocoupler, photocoupler, or optical isolator) is an electronic component that transfers electrical signals between two isolated circuits by using light. Opto-isolators prevent high voltages from affecting the system receiving the signal.
