  • Overview
  • Specifications
  • The Wolverine DDW-226-EX is an Industrial Ethernet Extender, powered by the Westermo WeOS network operating system. Independently tested for IECEX and ATEX by Baseefa, the Wolverine is the perfect solution for hazardous area applications in any part of the world.

    The DDW-226-EX allows effective Ethernet networks to be created over long distances (up to 15 km) at data rates up to 15.3 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 combination of WeOS and the integrated RS-232 port allows legacy equipment to become part of an IP backbone network.

    With its robust aluminium housing, the DDW-226-EX 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.

    Only industrial grade components are used which gives the DDW-226-EX an MTBF of 370,000 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 DDW-226-EX 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.
