I am having a little trouble understanding the working of the optocoupler module given in this link https://www.electronicscomp.com/pc8...mRYvi6suMKi7edd-tf3GEVsk_VxnCIoIaAoStEALw_wcB
I want to understand that how a micro controller will read the sensor working on 24 volt DC through this module.
I do not see the VCC supply pin at its output terminals. Anyone have any idea how to connect the output terminal of this model to the micro controller?
