Device description

The Open Rail Family RS20/RS30 offers you a variety of more than 450
switch models. You set up your own switch according to your requirements
regarding the number of ports, transmission speed, media type, connector
type, temperature range, certifications and software variant.
The RS20/RS30 devices are designed for the special requirements of
industrial automation. They meet the relevant industry standards, provide
very high operational reliability, even under extreme conditions, and also
long-term reliability and flexibility. The devices operate without fans and
have a redundant voltage supply. The switches are very quickly mounted
by snapping them onto a hat rail.
The HIPER-Ring redundancy concept enables you to quickly carry out a
reconfiguration, and also a simple configuration with only one additional
connection. The diagnosis display and the display of the operating
parameters and IP address information field provide a quick overview.
It can be easily managed via a Web browser, via Telnet, with a management
software product (such as F) or locally on the switch (V.24 interface).
The RS20/RS30 allows you to construct switched industrial ETHERNET
networks that conform to the IEEE 802.3 and 802.3u standards using
copper wires or optical fibers in a bus or ring topology. You can connect
terminal devices and other infrastructure components via twisted pair cables,
multi-mode LWL and single-mode LWL. The twisted pair ports support
autocrossing, autonegotiation and autopolarity.
