Description
±1 V A V: Voltage
1 to 5 V
± 10 V
B
The digitized analog values are listed in
the section "Representation of analog
values for analog input channels" in the
voltage measuring range.
2DMU: Current (2-wire
sensor)
4 to 20 mA D To supply these transducers with
current you must connect 24 V to the L+
and M front connector terminals.
The digitized analog values are listed in
the section "Representation of analog
values for analog input channels" in the
current measuring range.

the section "Representation of analog
values for analog input channels" in the
current measuring range.
Default
The module has the following default settings in
STEP 7
:
Measuring method "voltage"
Measuring range "± 10 V".
You can use this combination of measuring method and measuring range without configuring
