Note
• Terminals 42 / 52 have the same potential. Digital outputs
DO 41 / 42 and DO 51 / 52 are not electrically isolated from
each other. If an additional electrically isolated digital output
is required, a corresponding plug-in module must be used.
• If you are using a mechanical counter, we recommend setting
a pulse width of 30 ms and a maximum frequency of
f 30 Hz.
