11 Ports

11-port switch for Gigabit Ethernet with highest data throughput. The M12 network connections distribute data from one or two uplink ports to up to 10 or 9 devices respectively.

High-efficiency Layer 2 switch for fast and reliable networks with intelligent power management.



Optionally, the connected edge devices can also be powered via Power-over-Ethernet (PoE) according to IEEE 802.3af/at with up to 30 W per port.

Supported by a full set of robust M12 connectors for reliable connections.


24 - 110 VDC

The integrated wide-range power supply is fully compliant to EN 50155, Class S2 and tolerates interruptions of up to 10 ms.

The Ethernet switch is designed according to the international railway standard EN 50155. Components have to meet the strictest environmental requirements, e.g. an extended temperature range. In addition, they must be resilient to shocks and vibrations.
