In general, open PNP inputs are "LOW" and open NPN inputs are "HIGH."
The input stages are designed for electronic pulse generators.
Note for mechanical switching contacts:
If, in exceptional cases, mechanical contacts are to be used as a pulse source, a
commercially available external capacitor of approx. 10 µF must be installed at
the terminals between GND (-) and the corresponding input (+). This attenuates
the maximum input frequency to approximately 20 Hz and suppresses bouncing.
