Operator Interfaces, Switches & Relays


Compact industrial Ethernet switches

March 2009 Operator Interfaces, Switches & Relays

The Siemens Industry Automation Division has introduced various new innovations in its range of industrial Ethernet switches: the Scalance XB-000 range for low-cost design of small line and star topologies; the flatter design of the Scalance XF-200 range and an extension of the X-100 range for power supply over the Ethernet data line.

XB-000

The switches of the Scalance XB-000 range are unmanaged industrial Ethernet switches with IP20 protection, and are suitable for use in industrial environments which are not particularly harsh. Due to the compact box design the low-cost switches can be simply fitted on a standard DIN rail in a control cabinet. The XB005, XB008, XB004-1 and XB004-1LD versions have up to eight electrical RJ45 ports or four RJ45 ports and a fibre-optic port.

XF-200

The Scalance XF204IRT is the first switch from the new Scalance XF-200 range. It saves space as a result of its flat design with the cable outlet sloping downward, whereas the plugs are connected as usual from the front. The new switch allows users to design isochronous realtime Ethernet segments. The Scalance XF204IRT can be operated directly in a ring topology as a managed switch, and used for standby coupling with other network segments in order to guarantee high network availability. Furthermore, it offers all functions of the X-200 range, such as the built-in redundancy manager function.

X-100

An unmanaged switch with power-over-Ethernet function supplements the Scalance X-100 range. Two data terminals can then be powered over the Ethernet data line. As this is possible using the existing power supply for the switch, an additional 48 V supply is unnecessary, and costs are saved due to the omission of power supply units. The X108PoE switch is suitable for designing electrical star and line topologies in machine and plant components. The integral securing collars permit the connection of up to eight RJ45 FastConnect plugs. Just like all X-100 switches, it has a rugged metal housing with IP30 protection for space-saving installation in a control cabinet – either on a standard DIN rail, on an S7-300 rail or direct wall mounting.
