FLEXtraŽ FO, PROFIBUS Optical Hub
The FLEXtra® FO is a PROFIBUS repeater with the capability of expansion by 2 (FLEXtra® FO 650-2) or by 5 (FLEXtra® FO 650-5) optical MPI/PROFIBUS segments.
It translates an electrical MPI/PROFBUS interface into an optical MPI/PROFIBUS interface and vice-versa. The FLEXtra® FO permits transmission rates of 9.6 kbps to 12 Mbps on the PROFIBUS with automatic detection of the baud rate. With its optical signal transmission, it offers complete electrical isolation between the PROFIBUS stations and PROFIBUS sub networks.
A further advantage of the FLEXtra® FO is its being unaffected by EMC influences.
The transmission signals are converted into optical signals by the FLEXtra® FO and are transmitted on the FO line in this way. In addition the flank slope, level and duty cycle. of the signals are regenerated. The FLEXtra® FO is available with 3 different optical interfaces and can therefore also be perfectly combined with existing transmission systems. It is suitable for POF* and PCF* FO.
For the close range up to 65 m, an optical transmission line can be set up very quickly and without great effort using POF*. For longer distances up to 250 m, PCF* FOs can be used. The optical interface of the FLEXtra® FO transmits in the visual range (650 nm red light), which enables initial checking of the optical transmission line without expensive measuring instruments.
The FLEXtra® FO incorporates integrated status LEDs for every segment, for use in diagnosis. These provide a continual status of the busses and the optical interfaces and assist with detailed fault finding. The FLEXtra® FO also has DIP switches for disconnecting all or individual segments. The segments are disconnected but each segment remains separately functional.
