Thread: Opto isolator question
Threaded View

I'm hoping someone can point me in the right direction. I have an axbb which is great btw, I also bought a cheap 5 axis Bob to connect to port 3 to give me more inputs for the control panel. I thought I would use the additional outputs to light the control switches to show their active state and bought a cheap 4 channel opto isolator for the job. The Leds on the optoboard switch on when I activate the output but I can't seem to get the switch lights to work on the output side of the opto? I connected the output side G to -0v(24v) and the output side to the switch bulb with the other side of the bulb to +24v. Is this correct? Also I checked continuity on both grounds on input and output sides and they seem to be connected....is this right?
Cheers for any help you would like to give
