We are about to have to do another production run of our 8 Channel I/O and would like to get any input on what you would like to see done differently or new features you would like to see.
How well does this work for monitoring HVAC systems (24vac signals)? I have a multi Aqua chiller and I want to detect when some of the limit switches are tripped or not.
What opto isolator chip are you using?
It appears from the schematic that each channel is isolated (no common ground).
