Description
The digitized analog values
are listed in the section "Rep‐
resentation of analog values
for analog input channels" in
the voltage measuring range.
To supply these transducers
with current you must con‐
nect 24 V to the L+ and M
front connector terminals.
The digitized analog values
are listed in the section "Rep‐
resentation of analog values
for analog input channels" in
the current measuring range.
The digitized analog values
are listed in the section "Rep‐
resentation of analog values
for analog input channels" in
the current measuring range.
The digitized analog values
are listed in the section "Rep‐
resentation of analog values
for analog input channels" in
the resistance measuring
range.
The digitized analog values
are listed in the section "Rep‐
resentation of analog values
