Hi everyone,
I have a very simple circuit I need for automation purposes but my knowledge with transistors are very far in the past. I want to galvanically isolate a 0-24 VDC square wave signal using the following optocoupler : https://www.phoenixcontact.com/en-us/products/single-solid-state-relay-opt-24dc-24dc-2-2966595. Otherwise, I want a copy of my input on my output. My input maximum frequency is around 3 kHz, no big deal.
I searched and found out I can't use this optocoupler alone and I tried the following schematic which does not give me a square wave. I put a random resistor of 47k :
That does not output a square wave. Suggestions??
Thank you!
