Digital status inputs
All inputs are galvanically isolated from the computer, but not from each other. The
following can be used as signal transmitters: contact, open collector / drain, active
push / pull
-U max
5 V
-I max 13 mA
f max 10 Hz

Reserve signal inputs
The ERZ2000-NG offers additional free inputs for which the same data as for the
"normal" signal inputs applies. These free inputs can be assigned with functions and
events, statuses, additional counter, etc. can be detected and stored in DSfG ar-
chives.
