Description
The digitized analog values are lis‐
ted in the section "Representation
of analog values for analog input
channels" in the voltage measur‐
ing range.
To supply these transducers with
current you must connect 24 V to
the L+ and M front connector ter‐
minals.
The digitized analog values are lis‐
ted in the section "Representation
of analog values for analog input
channels" in the current measur‐
ing range.
The digitized analog values are lis‐
ted in the section "Representation
of analog values for analog input

ing range.
The digitized analog values are lis‐
ted in the section "Representation
of analog values for analog input
