Industrial Ethernet Extender Wolverine DDW-222

Industrial Ethernet Extender Wolverine DDW-222


The Industrial Ethernet Extender Wolverine DDW-222 allows effective Ethernet 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 integrated RS-232 port allows legacy equipment to become part of an IP backbone network.

With its robust aluminium housing, the Industrial Ethernet Extender Wolverine DDW-222 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-222 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-222 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.

For resilience, a ring of Industrial Ethernet Extender Wolverine DDW-222 can be created using the Westermo FRNT protocol. This is configured using the simple web interface. For network management, SNMP provides an industry standard solution allowing the westermo Wolverine DDW-222 to be used as part of a large network.
