November 13, 2017 - With its Scalance XB-100 product line, Siemens is launching a generation of unmanaged Industrial Ethernet switches designed to permit the configuration of electrical and optical line and star topologies in networks. This range of switches is particularly suited for use in industry and in building automation applications. Design features include a number of ports and interfaces, a plastic enclosure, and a design making it ideal for control cabinet mounting. The switches are also approved for use in potentially explosive atmospheres (ATEX Zone 2, IECEx). As unmanaged switches with no pre-configuration, the Scalance XB-100 products are suitable for immediate use, and come with Profinet CC-A conformity to ensure the reliable transmission of Profinet data.
The Scalance XB-100 switches are available in five different variants with up to 24 RJ45 ports as well as two ST/BFOC or two SC ports enabling distances of up to 5 kilometers to be bridged in multimode operation. All the switches are fitted with a redundant power supply, whether with direct current (DC) 24 volts or alternating current (AC) 24 volts, ensuring reliable operation even in the event of a power supply failure.
Support for AC 24 V (50/60 Hz) is particularly vital in the field of building automation, where the switch product line is suited for the connection of monitoring, closed and open-loop control, and also optimization devices over Ethernet using the protocol BACnet/IP.
The design of the unmanaged Industrial Ethernet switches not only allows them to be mounted on a 35 mm DIN rail, but also ensures compatibility with managed Layer 2 Scalance XB-200 Industrial Ethernet switches and the TIA (Totally Integrated Automation) environment. Diagnostic LEDs enable precise determination of the device status and diagnostic analysis.
