Product Information

Product Description

Authorized North America Distributor Stamp

The ComBricks 2 Channel PROFIBUS fiber optic module allow for fiber links up to 3 km using multimode cable. Fiber optics links and backbones are very useful in PROFIBUS installations where distance and/or grounding are a problem. This module enables long cable distances and a galvanic isolation between devices and segments. It is suitable for: point-to-point, bus, star and hub topologies.

The fiber optic modules can be placed side by side with standard or SCOPE copper repeater modules. Just like any other ComBricks module, the channels are directly connected with the ProfiTrace OE core in the Head Station. Busmonitor data is directly available in the web server.

ComBricks can easily be transformed to a fully dedicated fiber optic hub mixed with copper segments. The hub topology delivers an optimized delay time and live expansion.

The advanced 12 Mbps core of the fiber optic module can be cascaded unlimitedly with other fiber modules. It contains diagnostic LEDs and supports the redundancy feature. The fiber connection is utilized by 4 ST/BFOC connectors.
