The earliest opto-isolators, originally marketed as light cells, emerged in the 1960s. They employed miniature incandescent light bulbs as sources of light, and cadmium sulfide (CdS) or cadmium selenide (CdSe) photoresistors (also called light-dependent resistors, LDRs) as receivers. In applications where control linearity was not important, or where available current was too low for …
WebThe Optoisolators in this data sheet are UL recognised under E58730. This series is designed for transmission of information between one power supply voltage and another where the potentials during surge conditions are not greater than the guaranteed isolation voltage. ustom electrical, wire and cabling and connectors are available. WebOptocouplers are also called photodiodes, optoisolators, photocouplers, and optical isolators. A standard optocoupler such as PC817 supports up to 5 kV of input-output isolation voltage . [i] Most electronic components operate below 10 V, and if a lighting surge enters the system, it can induce voltages up to 10 KV – which is enough to fry ...
