I did not try that, and sorry I missed your previous post. I looked at those settings, but thought it was just for debounce.
So the 1ms default filter setting can prevent the module from reading a constant 24vdc at the input?
It did for me. Some research revealed that it is a known issue with those modules.
You're right though, the filter is designed for debounce, but apparently it either doesn't work correctly with these modules, or they are so sensitive that they somehow see jitter at the input such that they don't reliable turn on or off.
