Dear members. Could someone help me with the following issue?
I would like to control a optocoupler from an output of the MCP23017. When i search the internet i see so many diverent optocouplers i dont know which one i should select.
Important for me is that i can control him with 5Vdc, is 4pins pcb and that the emitor and collector is like a potential free contact like relay. Voltage true the E and C is maybe 24Vdc and low current.
I guess it isn’t difficult but I don’t know which optocoupler (opto-isolator) i should use.
Thank you in advance!!
