SIEMENS SIMATIC Programmable Logic Controllers S7-300 Signal Modules

SIEMENS S7-300 Signal Modules

Signal modules are the interface of the SIMATIC S7-300 to the process. The multi-facetted module range of S7-300 allows modular customization to suit the most varied tasks.
S7-300 supports multi-facetted technological tasks and offers exhaustive communication options. Apart from the CPUs with integrated functions and interfaces, there is a wide range of special modules in S7-300 design for technology and communication.

S7-300 modules exceed the specifications regarding transport and storage conditions pursuant to IEC 61131-2. The following information applies to modules that are transported and stored in their original packaging.
The climatic conditions for temperature and humidity meet:
● IEC 60721-3-3, Class 3K7 for storage.
● IEC 60721-3-2, Class 2K4 for transport.

  • Easy installation

The sensors/actuators are connected through front connectors. These are available for the following connection methods:

  • Screw-type terminals
  • Spring loaded
  • Fast Connect (insulation displacement )

When a module is replaced, the connector is simply plugged into the new module of the same type; the wiring is retained. The coding of the front connector avoids mistakes.
