WebThe principal idea is that when the switch, (or logic), is LOW, the optocoupler LED is ON. R1 is the LED current limitor resistance, (you need to dimension it to your own demands). The output is now ON thus giving 0V at pin 8 to the GATE With the switch, (or logic), is HIGH, (or no potential at all), the output at pin 8 is OFF. WebProgrammable logic controller (PLC) is a control system using electronic operations. Its easy storing procedures, handy extending principles, functions of sequential/position …

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 … WebHigh-speed rugged industrial-grade opto-isolated RS232 to RS485 / RS422 converter.
