S7-400 Analog modules

Range of modules

Description

S7-400 Analogbaugruppen

More complex tasks require the processing of analog process signals. Analog actuators and sensors can be connected to a SIMATIC S7-400 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. Analog output modules control 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 analog input/output modules exhibit the following mechanical characteristics::

Compact design
The rugged sturdy plastic housing features:
Labeling strips for inserting in front connector (included in scope of delivery; also as template in manual); cover films also available.

Easy assembly
Modules are hung into the rack and screwed into place.

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.
