New low-cost Scalance XB-000 industrial Ethernet switches

The Siemens Industry Automation Division is expanding its range of industrial Ethernet switches with the new Scalance XB-000 range for low-cost design of small line and star topologies and the new Scalance XF-200 range with flat design. Furthermore, the Division has extended its existing X-100 range with a compact switch for power supply over the Ethernet data line.

Suitable for use in industrial environments that are not particularly harsh, the switches of the Scalance XB-000 range are unmanaged industrial Ethernet switches with IP20 protection. Due to the compact box design, the low-cost switches can be fitted simply 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.

Within the new Scalance XF-200 range, the Scalance XF204IRT is the first switch. 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 enables users to design isochronous real-time 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 the functions of the X-200 range, such as the built-in redundancy manager function.

An unmanaged switch with power-over-Ethernet (PoE) 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 48V 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 with direct wall mounting.
