Description
Westermo Profibus DP Multidrop & Redundant Ring 5km Multimode Fiber Interface, LC Connector.
The ODW-612 is a fiber optic modem that can be used to create either redundant ring or multidrop fiber optic solutions for devices with PROFIBUS DP interfaces
The ODW-612 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 a fiber link depends on selected transceiver and fiber type. Fiber distances up to 80 km (50 miles) are possible on each leg of the
ring meaning huge rings over 1000 km (621.4 miles) in circumference could be
created.
The ODW-612 is able to automatically detect the data rate of the connected
PROFIBUS DP device and hence needs minimal configuration prior to use. The
unit also has a re-timing function that eliminates the problem of jitter and hence
ensures reliable communications in all situations.
The unit has LED indication to display fault conditions as well as relay contacts
that can be connected to a PLC or similar device to allow network problems to
be diagnosed at a central point. It is possible to use the ODW-611 at start/end
points in a multidrop application together with ODW-612.
