R
bias
Bias resistor (with a resist-
ance of 24.9 kΩ in the case of
NTC10 kΩ and NTC20 kΩ or
7.5 kΩ for PT/NI1000 sensors)
can be switched off via the
software through S1 to support
0–10 V inputs without bias
(“high impedance”).
R
serial
Serial resistor for voltage sepa-
ration and filtering
(with a resistance of 150 kΩ).
R
downstream
An internal load resistor (with a
resistance of 50 kΩ). De
-
pending on the type of sensor
connected, the firmware can
switch this resistor off for type 8
universal inputs.
