In the description about the Opto-isolator:

“this allows the low-voltage side to control a high voltage side”…

So, how mutch “high voltage” can I control (I’m hoping for24V)?

Is there any restrictions about the current on the “high voltage” side?

I’m not an electrician, so please be basic…

Hi Pajen!

So, how mutch “high voltage” can I control (I’m hoping for24V)?

24 volts would be fine. I stay below 36 volts to be safe

Is there any restrictions about the current on the “high voltage” side?

600mA is what the output transistors are rated for but I'd shoot for 450 or lower.

Hope this helps!
