WebThe main purpose of an optical isolation circuit on a digital input card in a PLC I/O system is: a) to provide a common reference point for DC signals b) to isolate the low-voltage … 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.
