Westermo ODW-641 fibre optic modem certified for use with ABB 800xA DCS


*The ODW-641 is a fibre optic modem designed for point to point fibre optic connec-tions between PROFIBUS-DP networks.The ODW-641 is designed for harsh industrial usage as well as road or railway installations meeting industrial level EMC specifications and having a wide operating temperature range.The maximum distance of the fibre link depends on selected transceiver and fibretype.Fibre distances up to 80 km (50 miles) are possible using singlemode fibre.The ODW-641 is able to automatically detect the data rate of the connected PROFIBUS-DP network and hence needs minimal configuration prior to use.The unit also has a retiming function that eliminates the problem of jitter and hence ensures reliable communications in all situations.

Note that ODW-641 is not compatible with ODW-611. This device can be used in ODW-641 point-to-point applications or in combination with ODW-642. Automatic data rate detection and retiming.
