Use shielded cables!

is calculated as follows:
R

•
Can also be set as status output; for the electrical connection refer to status output
connection diagram.
INFORMATION!
•
For frequencies above 100 Hz, shielded cables are to be used in order to reduce effects from
electrical interferences (EMC).
•
Shielding takes place at the electrical connection (S) of the output terminal block.
INFORMATION!
•
Independent of connection polarity.
•
The output is open if the signal converter is not powered.
