Isolated Inputs Ardbox/M-Duino

Isolated Inputs Ardbox/M-Duino

In this post it is described how to use the galvanically isolated inputs in Idustrial Shields PLCs (Ardbox and M-Duino). As shown in the Figure below, isolated inputs always have two available connections and both of these connections need to be wired for a proper performance of the inputs. The configuration if the inputs is PNP. All isolated inputs are DIGITAL,  not ANALOG. Ix.x    –> Signal. Voltage up to 24V (-) Ix.x –> reference or COM of the input signal.   IMPORTANT:…
