Weidmuller adds Gigabit switches and power-over-Ethernet switches

07 April 2011

Weidmuller has added new high-performance products to its industrial Ethernet family of active products, including new Gigabit and power-over-Ethernet (PoE) switches. The Gigabit Ethernet switches provide a high-performance connection to the factory infrastructure, while the PoE devices facilitate easy operation of field-level devices.

Weidmüller’s unmanaged and managed Gigabit switches (top picture) offer excellent network performance, security and reliability and are suitable for networks involving highdata communications volumes in both branched subnets, as well as backbone applications. The switches support the use of many common TCP/IP based industrial network protocols, for example, EtherNet/IP and Modbus/TCP, enabling their use in a wide variety of applications.

Weidmuller Gigabit switches at a glance:
 All-purpose usage - A wide variety of unmanaged 5-port gigabit switches and managed 9-port full-gigabit switches ensure there is the suitable module available for every application.
 Worldwide use - International approvals – ATEX, UL, Class I, Div. 2, DNV and GL – enable worldwide use.
 Variable connection options - Universal connection options to the backbone via two gigabit combo ports with interfaces for connecting copper or fiber optic cables.
 Plug and Play configuration - An external memory and configuration module supports the simple replacement and update of a switch configuration.
 Fault tolerance - The highest level of network availability is provided by the ring redundancy topology with a recovery time of less than 20 ms.

In addition, Weidmuller's NET Manager software is available to manage your Ethernet networks:
 Automatic topology recognition and visualisation
 Event notification in real time
 Centralised configuration and Firmware administration
 Data communication reports and event logs
 High-end switch functionality - Universal application options in industrial and backbone networks.
The company's PoE switches (lower picture) operate from 24V supplies and feed power to PoE enabled Ethernet devices with up to 30W input power. The managed version also enables remote on/off functionality and resetting of connected PoE devices via SNMP, Web interface or via HMI/SCADA systems in combination with SNMP OPC.
Weidmuller PoE switches at a glance:
 Reduced wiring - The power supply of PoE compatible end devices comes from the data cable (such as WLAN access points); this reduces the wiring work. 
 All-purpose usage - Managed and unmanaged versions offer universal deployment options for PoE switches.
 24 V power supply for PoE - To enable simple integration in standard electrical cabinets, the PoE voltage can be provided by a wide range input between 24 V to 48 V.
 IEEE 802.3at/af compatibility - The extended power rating of 30 W per PoE port allows connection of PoE devices with power requirements exceeding 15 W.
 Additional PoE functionality - For more control of field functions such as switching PoE ports on/off;  the managed versions offer status control of PoE end devices including alarm signalling and power consumption restriction.
