The SCALANCE XR-300PoE is ideal for use in plant networks and for integrating the industrial network into an existing corporate network. Both at the field level and the control level, the switch networks the distributed field devices and ensures high plant availability with extensive diagnostics options and high transmission speeds. The modularity permits perfect adaptation to the respective application through the use of electrical as well as optical media modules.

The SCALANCE XR-300PoE supplies PoE-compatible devices, such as IWLAN access points SCALANCE W, IP cameras and IP telephones, with power over the data cable and is suitable for configuring electrical and/or optical Industrial Ethernet line, star or ring structures with up to 24 ports, of which 16 RJ45 ports are pre-assigned. Eight of these support PoE. The switch can be optionally equipped with four electrical and/or optical 2-port media modules. It can also be used as a hub in the plant bus (redundant connection is possible).

The SCALANCE XR324-4M PoE TS (Transportation Systems) is suitable for use in railway applications thanks to its specification according to EN 50155 and EN 50121-4. Media modules that have been approved for railway applications must be used.

Supply of terminal devices with PoE by means of PoE-compatible switches

The use of media modules in partly and fully modular versions of the SCALANCE X-300 switches supports:

• The extension of networks by subsequent insertion of additional media modules in unused media module slots
• The changing of cabling technology, e.g. conversion from copper to fiber-optic cables, or from multimode to single-mode FOC
