11 Cable lengths
For applications which use clock outputs S11 and S21, the cables may have
an overall length of up to 500 m (per channel).
If no clock outputs are used, the maximum cable length can be calculated
using the total permissible resistance (500
Ω ).
The aforementioned values are intended as a guide.
Depending on the wiring and installation of the cable, different lengths can
be achieved.
Path Maximum cable length Cable resistance
A1 — S34 1 km 500 Ω
A1 — S35 500 Ω
S11— S12
S21 — S22 500 m
without external wiring
500 Ω
S21 — S22 > 500 m
wiring with an external resistance of 1 k Ω
from S11 to A2 and from S21 to A2.
