I am using a Kanalog Kflop to power my CNC. I have a lot of inputs coming to the board.
I want to use JP4 and JP6 as inputs so I want to find an opto isolated board that works with the 3.3V of JP4 to connect my inputs to. I am using 24VDC in my machine.
Thank you in advance,
Jad

Hi Jad,
I haven't used this, but I believe it could work:

I can't find the
connector or output specification. But I believe it has TTL outputs. You would need to test the output voltage to see if it is safe for 3.3V KFLOP inputs. If the outputs don't go above 3.8V under a 150 ohm load then they could be connected directly to KFLOP JP4.
