FLEXtra® twinRepeater

Despite its small size, the FLEXtra® twinRepeater is a full PROFIBUS repeater designed for mounting on a DIN rail.

It regenerates the incoming electrical signal on a bus line and retransmits it (bit reshaping and retransmission).
The signals are restored in level, slope, and duty cycle.
The FLEXtra® twinRepeater supports data rates of 9.6 kbps to 12 Mbps and recognizes them automatically.
It can be used for bus extension (up to 1 km with 2 FLEXtra® twinRepeaters), to increase the number of participants, and to expand the system. At the same time, use in MPI networks is possible. As a special application option, the FLEXtra® twinRepeater allows the setup of stubs as separate segments.
The status LEDs integrated for each segment provide a quick overview of the current bus status. Furthermore, the FLEXtra® twinRepeater provides electrical isolation between the two PROFIBUS segments.
In addition, it has a switch to turn off the repeating function. The segments are separated but continue to function for themselves.
PROFIBUS connectors are required for connection to the PROFIBUS cable.
