Industrial Ethernet Extender Wolverine DDW-220

Industrial Ethernet Extender Wolverine DDW-220


The Industrial Ethernet Extender Wolverine DDW-220 allows effective Ethernet Extender networks to be created over long distances (up to 15 km) at data rates up to 5.7 Mbit/s. The SHDSL technology makes it possible to reuse many types of pre-existing copper cables which can lead to considerable financial savings. Dependent on cable characteristics, distances up to 15 km (9.3 mi) can be achieved. The protocol transparent link allows any industrial protocol to pass unhindered ensuring the unit is easy to use.

With its robust aluminium housing, the Industrial Ethernet Extender Wolverine DDW-220 is designed for use in heavy duty industrial applications. The wide power range and I/O fault contact make it ideal for easy installation and monitoring in industrial applications. The Transient Blocking Unit (TBU) is acknowledged as the most effective form of protection against damaging noise spikes caused by lightning or high voltage equipment.

Only industrial grade components are used which gives the Industrial Ethernet Extender Wolverine DDW-220 an MTBF of 700,000 hours and ensures a long service life. A wide operating temperature range of –40 to +70°C (–40 to +158°F) can be achieved without the need for moving parts or cooling holes in the case. The Industrial Ethernet Extender Wolverine DDW-220 has been tested both by Westermo and external test houses to meet many EMC, isolation, vibration and shock standards, all to the highest levels suitable for heavy industrial environments.

The Industrial Ethernet Extender Wolverine DDW-220 is designed for daisy chain applications over an SHDSL line. At each location, a local network can then be configured using the integrated L2 switch. The switches support QoS (Quality of Service) with four priority queues and strict priority scheduling as well as HoL (Head of Line Blocking Prevention).
