SIMATIC S7Ć300
Analog input/output modules
General
Overview
www.DataSheet4U.com
• Analog inputs and outputs
for the S7Ć300
• For solving even more comĆ
plex tasks involving analog
process signals
• For connecting analog acĆ
tuators and sensors without
additional amplifiers
Application
Design
Analog I/O modules contain
analog inputs/outputs for the
SIMATIC S7Ć300. Analog senĆ
sors and actuators can be
connected to the SIMATIC
S7Ć300 via these modules.
Analog I/O modules offer the
user the following advantages:
S Optimal adaptation;
the number of inputs/outputs
can be adapted to the task
via modules that can be
combined in any way. There
is no need for surplus inĆ
vestment.
S Powerful analog technology;
different I/O areas and high
resolution enable connection
of a wide variety of analog
sensors and actuators
Analog input modules are
characterized by the following
mechanical features:
Compact design;
the rugged plastic housing
contains:
S Red LEDs for group faults/
errors
S Front connector protected
by the front panel
S Labeling area on the front
panel
Easy assembly;
the module is mounted on the
DIN rail and connected to the
adjacent modules via bus
connectors. There are no slot
rules: The input addresses
are defined by the slots.
UserĆfriednly wiring;
the modules are wired by
means of a plugĆin front conĆ
nector. When the connector is
plugged in for the first time, a
coding element engages so
that the connector can only be
plugged into modules of the
same type.
When the module is replaced,
the front connector can be
used in its fully wired state for
the new module of the same
type.

Application
The analog input/output moĆ
dule converts
S analog signals from the proĆ
cess to digital values for the
S7Ć300, and
S digital signals from the
S7Ć300 to analog signals
for the process.
Function
The analog input/output moĆ
dule also includes:
S 4 inputs, 2 outputs
S 8Ćbit input resolution
S 8Ćbit output resolution
S Measuring ranges of 0 to
10 V or 0 to 20 mA:
The range is selected by
means of the appropriate
connections on the module.
