Neon bulbs with a maximum residual current of 2 mA/1 mA
at 230 V/115 V can be connected to I7 and I8.
Two-wire proximity switches have a residual current with the
“0” state. If this residual current is too high, the easy input
may detect a “1” signal.
Therefore, use inputs I7 and I8. An additional input circuit is
required if more inputs are used.
Increasing the input current
The following input circuit can be used in order to prevent
interference and also when using two-wire proximity
switches:

Always use neon bulbs that are operated with a separate
N connection.
Caution!
Do not use reed relay contacts on I7, I8. These may burn
or melt due to the high inrush current of I7, I8.
