Westermo DDW-142-12VDC-BP.

Industrial Ethernet extender with bypass relay.

Westermo’s Ethernet extender technology based on SHDSL makes it possible to reuse many types of pre-existing copper cables, which can lead to considerable financial savings when installing new or updating existing systems.
The SHDSL technology enables long distance connections of Ethernet interface (up to 15 km/9.3 mi) at data rates up to 15.3 Mbit/s on a single twisted pair cable.
By using two pairs “bonded”, this rate can be doubled up to 30.6 Mbit/s.
The built-in switch allows two Ethernet devices to be attached.
The DDW-x42 series also supports one serial RS-232 or RS-485 interface.

Only industrial-grade components are used which ensures a long service life and an MTBF (Mean Time Between Failures) of up to 437,000 hours according to the though military standard MIL-HDBK-217.
A wide operating temperature range up to -40 to +74°C (-40 to +165°F) is supported with no moving parts or ventilation holes in the case.

The DDW-x42 series is often used in applications on railways, roads or with utilities where failure could result in significant costs.
To ensure reliable operation, the DDW-x42 series has been tested both by Westermo and external test labs to meet the most recognized standards related to EMC, isolation, vibration and shock.
All to the highest levels suitable for the though applications the product is designed for.

The DDW-x42 series is powered by Westermo Operating System, WeOS.
WeOS delivers unique security functionality as well as allowing the products to form part of a resilient multimedia ring network using the Westermo FRNT protocol or industry standard STP/RSTP.
In addition, it contains amazing serial connectivity capability – from being able to simulate an old AT modem, convert Modbus RTU to TCP or encapsulate serial data into an IP packets.
The DDW-x42 series is incredibly flexible and easy to use.
A basic point-to-point or multidrop network can be created without the need for any kind of configuration.
