September 2008 Fieldbus & Industrial Networking

The new WAGO 852 Series of products, ranging from simple Ethernet switches to configurable Ethernet communication all-rounders, provide comprehensive and scalable network infrastructure solutions.

The 852 Series includes an Ethernet switch featuring five or eight 10/100BaseTX ports as well as an eight-port switch equipped with two additional ports for SFP (small form pluggable) modules used to connect fibre-optic cables. A configurable Ethernet switch featuring seven 10/100BaseTX ports and two SFP 100Base-FX ports completes the 852 Series. Retro-fit modules, including interfaces for different optical fibres, are available for both versions featuring SFP ports.

All modules are designed for industrial applications. They have robust enclosures, redundant voltage supplies ranging from 9 to 48 V and function monitoring with relay. Alarm functions are enabled via a DIP switch. Features such as the auto-negotiation and auto-MDI/MDIX (crossover) on all 10/100BaseTX ports, as well as a store-and-forward switching mode are available. All devices are fully compliant with IEEE802.3 and 802.3u standards.

The configurable version offers various settings such as Xpress Ring. This allows the redundant ring to be configured, which enables a reconfiguration in less than 50 ms in the event of a primary link failure. Furthermore, failures can be reported via e-mail.
