Cost-effective managed switches

April 2010 Fieldbus & Industrial Networking

Profitek has introduced a Hirschmann RSB20 family of managed basic switches to offer overall cost efficiency coupled with high operational safety and availability in a wide range of applications.

The new family comprises 32 models distinguished by the number and type of ports offered as well as by their factory settings for EtherNet/IP and specific operating temperature ranges. All RSB20 switches support Fast Ethernet (10/100 BASE-TX, 100 BASE-FX) and offer both comprehensive management and redundancy modes as well as various different functions for convenient configuration and diagnostics. Supplied in a rugged and compact housing, they can be mounted on standard DIN rail.

Redundancy procedures, such as HIPER Ring, MRP (IEC ring function) and Rapid Spanning Tree, provide for high network availability. Access control is realised by means of SNMP V3. CLI (Command Line Interface), web browser and software tools, including HiVision or HiDiscovery, serve for comprehensive management, configuration and diagnostic functions.

Basic switches are now available for customised communications solutions. “While these switches complement our portfolio at the lower end, they require no compromises in quality, as demonstrated by an excellent MTBF (Mean Time Between Failures) of more than 50 years,” says Profitek’s sales director, Fons de Leeuw. “The family provides an entry into the segment of managed switches at an attractive cost, since customers pay only for the range of features they really need.”

Depending on the version, the switches feature eight or nine ports and up to three fibre uplinks. User can select between RJ45 connections, fibre uplinks for single or multimode and ports for SFP fibre optical transceivers. Passive cooling (no fans) and a redundant 12/24 VDC power supply ensure high operational safety.

All configuration data can be saved and recalled, if required, through a serial interface connecting to the ACA 11 auto-configuration adapter. The versatile, cost-efficient new family finds a fit in a wide range of applications, such as those found in mechanical engineering and the wind energy industry.

Operating temperature range is either 0 to 60°C or -40 to +70°C. Housing dimensions are 47/74x135x111 mm.
