Profibus Repeater

Profibus-DP Compact Repeater

The patented Profibus compact repeater offers transfer rates of 9.6kbps to 12Mbps. The transmission signals are regenerated by the repeater and re-sent so that faults in the line are largely eliminated. It is a great alternative to conventional repeaters due to its performance, size and price. It can be used for bus extension (up to 1 km with 2 PROFIBUS compact repeaters), to increase the number of participants, and to expand the system. MPI networks are supported. The compact repeater allows separate segments, which can be plugged directly into the PG connection of an existing Profibus connector. Due to the compact design, no additional space is needed in the control cabinet. Additionally no separate power is required, because the Profibus compact repeater uses the 5V power supply. The integrated status LEDs provide a quick overview on the current bus status.
