General Recommendations for Signal and Data Cable
Signal Connection
The following standard minimum requirements for the used type of cable are
recommended for the signal connection with external transmitters and sen-
sors as well as for the signal connection of external devices:
•
signal cable with a line-to-line capacity smaller than 120 pF/m and
an inductance smaller than 0.7 µH/m
•
Wire diameter greater or equal to 0.5 mm
ding to the application, stranded cable, shielded together. Screen at
just one place (preferably on FC1) connected with PE.
•
The maximum cable length is dependent on the type of the signal;
refer to the following section for exact specifications.
Data Communication Connection
The following standard minimum requirements for the used type of cable are
recommended for the data communication connection with external sensors
as well as for the data communication connection of external devices accor-
ding to RS232, RS422 or RS485:
•
signal cable with a line-to-line capacity smaller than 120 pF/m and
an inductance smaller than 0.7 µH/m
•
Wire diameter greater or equal to 0.25 mm
ding to the application, stranded cable, shielded together. Screen at
just one place (preferably on FC1) connected with PE.
