-The digital inputs are isolated by optocouplers. DC 0~40V in the specification is the input circuit's operating voltage range; the wiring below is an example using a DC 5~24V sensor supply. The input is recognized as HIGH when the voltage between the input terminal and COM is at least DC 5V. Select NPN or PNP operation by wiring COM accordingly. The PNP and NPN diagrams show alternative wiring methods. COM0 and COM1 are electrically the same common net, so both terminals must use the same polarity in an actual installation. Never connect opposite polarities to those terminals at the same time.
