Seeking help with opto-isolator issues

2017-10-28View Original

Thread Content

The ICC212 optoisolator has a 6mA supply voltage at the input and 4.2V at the output, but there is no current at the output – what’s going on? Do I need to connect a resistor?

First, untangle all the cables and use a signal generator to send signals in order to determine whether the isolator is functioning properly.
