Notice!
The maximum cable length of all inputs connected to the loop or stub is 500 m in total.
Additionally, all outputs which are not electrically isolated from LSN must be included in the
total line length calculation (e.g. peripherals connected via C points).
The activation of the inputs IN 1 - 8 has to be carried out electrically isolated from LSN (e.g.
with relay contact, pushbutton, etc.).
The inputs must have a minimum activation time of 3.2 s.
