Hello, I have a device (A) which outputs a constant voltage of 14VDC and switches to 24VDC when a programmed value is read by it. I want to feed this as an input to a PLC unit (B). The trouble is the PLC simply reads input voltage as 0=0 or "value"=1. I cannot specify a voltage threshold on the inp…
