SCALANCE XR524‑8C and SCALANCE XR552‑12M

Functional overview of SCALANCE X-500

The high-performance, fully/partially modular Industrial Ethernet switches of the SCALANCE X‑500 product line are suitable for designing electrical and optical line, ring and star topologies with high transmission rates up to 10 Gbps.

The devices are designed for high system availability, and are suitable for networking system components and distributed field devices in an industrial network as well as for integrating the industrial network in a corporate network. They have extensive diagnostics facilities.

To increase network availability, as many as 50 X‑200, X‑300, X-400 or X‑500 switches cascaded in line can be connected in a ring (Ethernet with fast media redundancy). Several rings can be redundantly linked through the standby function. Up to 52 nodes or subnets can be electrically connected with a SCALANCE XR-500 as star point in a star topology.

The modularity and scalability of the SCALANCE XR‑500 enable application-specific adaptation and expansion of the device configuration.

SCALANCE XR‑500 product overview

The basic types of SCALANCE XR‑500 designed for installation in 19" control cabinets correspond to IP20 protection. The data ports are either at the front or rear depending on the device version. Further expansion of the ports is possible using SFP or SFP+ plug-in transceivers and 4‑port media modules (electrical or optical).

The SCALANCE XR‑500 devices differ as follows with regard to the number and type of slots:

• SCALANCE XR552‑12M (ports at front/rear)
  Fully modular; 4 integrated SFP+ slots for optical SFP (1 Gbps) or SFP+ (10 Gbps) plug-in transceivers
  12 slots for 4-port media modules 10/100/1000 Mbps, electrical or optical
• SCALANCE XR528‑6M (ports at front/rear)
  Fully modular; 4 integrated SFP+ slots for optical SFP (1 Gbps) or SFP+ (10 Gbps) plug-in transceivers
  6 slots for 4-port media modules 10/100/1000 Mbps, electrical or optical
• SCALANCE XR526‑-8C
  Partially modular; 26 ports in total: 16 electrical ports 10/100/1000 Mbps (RJ45) and 8 combo ports 10/100/1000 Mbps (optical with SFP plug-in transceiver or electrical with RJ45); 2 electrical ports 10/100/1000/10,000 Mbps (optical with SFP plug-in transceiver or electrical with RJ45); built-in power unit (versions: 230 V AC, 230 V AC redundant or 24 V DC redundant)
• SCALANCE XR524‑8C
  Partially modular; 24 ports in total: 16 electrical ports 10/100/1000 Mbps (RJ45) and 8 combo ports 10/100/1000 Mbps (optical with SFP plug-in transceiver or electrical);
  built-in power unit (versions: 230 V AC, 230 V AC redundant or 24 V DC redundant)

The PS598 24 V DC power supply which is also optimized for the 19" control cabinet and provided with a wide-range input (85 to 264 V AC) can be used for single or redundant configuration. It can be mounted either directly on the rear of the SCALANCE XR‑500 or connected via cables.
