Hirschmann Industrial Ethernet Rail Switch RS20 Basic Family

Device description

The RS20 Basic 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

provide long-term reliability and flexibility.

The devices allow you to set up switched industrial Ethernet networks that

conform to the IEEE 802.3 standard using copper wires or optical fibers in a

line or ring structure.

The devices work without a fan.

The voltage is supplied redundantly.

The devices are mounted very quickly by snapping them onto the DIN rail.

Depending on the device variant, you can choose various media to connect

terminal devices and other infrastructure components:

 twisted pair cable

 multimode F/O

 singlemode F/O

The twisted pair ports support:

 Autocrossing

 Autonegotiation

 Autopolarity

There are convenient options for managing the device. Administer your

devices via:

 a Web browser

 HiDiscovery (software for setting up operation of the device)

 management software (e.g. Industrial HiVision)

 a V.24 interface (locally on the device)

The ring redundancy concept allows the network to be reconfigured quickly

after a failure.

Product configuration data can be provided by:

 diagnosis displays

 displaying the operating parameters

 a label area for the IP address

The devices provide you with a large range of functions. Information

pertaining to these functions is found in the relevant operating software

manuals. These manuals are available as PDF files on the CD ROM

provided, or you can download them from the Internet on the Hirschmann

product pages (www.hirschmann.com).

The Hirschmann network components help you ensure continuous

communication across all levels of the company network.

Description of the device variants

The devices differ with regard to the number of interfaces and the media type

for connecting segments.

There is a variant of the device with 4 ports available, and a variant with 8

ports. The table below shows the number and type of the ports you can

choose. In the column for the port type, the abbreviations F/O (optical fiber)

and TP (twisted pair) indicate the media type, while the abbreviations DSC

and RJ45 indicate the socket type.
