11 XN-322-20DI-PCNT digital input module with counter
XN-322-20DI-PCNT digital input modules have 20 inputs, for a +24 V level,
that can be used to read the logical low and logical high signal levels, i.e., 0
and 1. The modules feature input filters designed to suppress glitches on
the corresponding signal cables. In addition, digital inputs 1 – 4 feature a
counter function that, when used, makes internal module registers be incre-
mented every time there is an input pulse.
