Digital output module 4 DO-PN-2A

Description

Each channel can be switched between positive and negative switching. This allows, among other things, a switch in rotational direction if an DC motor is connected between two outputs. For this purpose, an output byte is reserved for the physical outputs, and each channel is assigned two bits in this byte. The switching characteristics of each output are set in the low nibble of the byte. If a bit is set, the corresponding channel has positive switching, if it is 0 then it has negative switching. The outputs are switched in the high nibble.
