Hi Guys
I want to connect my KC868-AI to a couple of output expanders on my alarm panel.
The alarm provides a -ve switched output.
I am considering, given that the KC868 will get 12v from the alarm panel (ie common power rails), I can just use the switched negative to the KC868 input, as that will pull it low.
First question - are the inputs "KCOM" black connector tied to the KC868 power supply input ground or are they isolated?
Second question - do you think its probable that I can just connect the alarm panel output to the KC868 input, and leave the "KCOM" black connector empty, and hope/assume the input will float high, and get pulled low to switch the KC868 when the panel pulls it low?
Many thanks for your thoughts.
