FLEXtra Profibus-DP Twin Repeater

Despite its small size, the FLEXtra twinRepeater is a full PROFIBUS repeater designed for DIN rail mounting. It regenerates the incoming electrical signal on a bus line and re-transmits it. The FLEXtra® twinRepeater supports data rates from 9.6kbps to 12Mbps 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. Use in MPI networks is supported. The status LEDs provide a quick overview of the current bus status. Electrical isolation between the two PROFIBUS segments is provided. A switch allows the repeating function to be disabled.
