The foundation for powerful networks

SCALANCE X-400 switches let you design networks in the Control Level area and ensure maximum availability. Thanks to the scalability of the basic unit and the optional Layer 3 switching function, the network can be built specifically for relevant particular application or extended at any time. Its comboports permit electrical or optical networking, even during operation (hot swappable). The switches in the SCALANCE X-400 family are closely based on the design of the SIMATIC S7-1500 family of controllers, from the lettering on the controls to the structure of the rail mounting.

Port Extender

Thanks to their modular architecture, SCALANCE X-400 switches allow for tool-free expansion with port extenders. The following port extenders are available to extend the basic devices to a maximum of 24 ports: 

  • Port extender PE408: eight additional RJ45 ports
  • Port extender PE400-8SFP: eight additional SFP slots
  • Port Extender PE408PoE: eight additional RJ45 ports with PoE according to IEEE 802.3at Type 2 (suitable SCALANCE power supplies available separately)

Typical uses

SCALANCE X-400 switches come with high performance (1 Gbit/s) and small space requirement – and they’re also compact for rail-mounting. Even large production networks can be easily and clearly structured thanks to their VLAN functionality (virtual segmentation).

FastConnect – a cabling system gets the hang

Structured cabling is the basis of an industrial bus system or network and must fulfill much higher requirements than cabling in the office area. Stringent demands are placed on the installation of cables in the industrial environment. Siemens offers FastConnect, a system that fulfills all these requirements: On-site assembly – quick, easy and error-free.

PLUGs for network components

Swap devices easily with no need for special knowledge: The C-PLUG, KEY-PLUG, and SCALANCE CLP removable storage media save the configuration data from your SCALANCE devices. Remove PLUG, install replacement device, insert PLUG – and the new device is ready to go! The KEY-PLUGs include all the functions of the C-PLUG and also enable specific functions like Layer 3 in the SCALANCE X-400.

Plug-in transceivers

Plug-in transceivers allow you to flexibly equip network components of the SCALANCE family with a corresponding SFP slot for optical connections.  Appropriate plug-in transceivers with a range of connections (SC, ST/BFOC and LC available) ensure maximum flexibility in your automation network.

Power supply for SCALANCE X-400

The SCALANCE PS924 PoE and PS9230 PoE power supplies have an output voltage of 54 V DC, which is needed in particular for Power-over-Ethernet (PoE) in accordance with the IEEE 802.3at standard. This reduces cabling costs, because the supply voltage is also transmitted via the data line.
