S7-300 Signal modules
More complex tasks require the processing of analog process signals. Analog actuators and sensors can be connected to a SIMATIC S7-300 via analog modules without additional amplifiers. The extensive range of modules allows the most suitable signal module to be selected in each case.
Area of application
Analog input modules facilitate connection of the controller to the analog signals of a process. They are suitable for connecting analog sensors such as voltage and current sensors, thermocouples, resistors and resistance thermometers as well as analog actuators.
Benefits
The use of analog input/output modules provides the user with the following advantages:
-
Optimum adaptation:
Since almost any combination of modules is possible, the number of inputs/outputs can be matched to suit the task in hand. Superfluous investments no longer exist -
High-performance analog technology:
A variety of input/output ranges and high resolution facilitate connection of a multitude of analog sensors and actuators
Design and functions
The use of analog input/output modules provides the user with the following advantages:
-
Red LED for group faults
-
Slot for the front connector, protected by the front cover
-
Labeling area on the front cover
When used in the ET 200M distributed I/O station together with active bus modules, the modules can be hot-swopped during operation without affecting the other modules.
User-friendly wiring
The modules are wired by means of a front connector. When they are first plugged in, a coding element clicks into place so that the connector will only fit into modules of the same type. When the module is replaced, the front connector can be used in its fully wired state for a new module of the same type.
