Unconnected analog inputs have a default
voltage of 8.5 V.
L
This is interpreted by the controller as a
logical status of '1'. This means that, in
general, no external relay is needed for
N
normally-closed contacts.
NOTE:
The relay contact must be suitable for
switching low voltage. For long cable
distances the analog input signal may be
sensitive to interference. In this case, an
external relay may also be used for
+10 V
normally-closed contacts.
