The ComBricks PROFIBUS DP/Fiber Coupler can be used to create one or two fiber optic links of up to 3 km each to extend a PROFIBUS DP network. Fiber links are also useful in installations with grounding problems or are otherwise in need of galvanic isolation. With the Monitoring Option, the network can also be monitored using ProfiTrace OE from a web-browser.

The coupler comes complete with a ComBricks Head Station (type 1A or type 1C - with monitoring), a PROFIBUS DP 1-Channel Repeater Module, and a 2 Channel Fiber Optic Module.

With the monitoring option, you get ProfiTrace OE and the PROFIBUS live list, statistics and email/SNMP event notification. In addition, there is one relay on the Head Station that can be used to turn on a light tower or a back-up system, etc. in response to network events such as station lost, syncs,etc. If more relays are needed, just snap in a 4 channel relay module!

Snap in additional Fiber Optic Modules to create other topologies including redundant point-to-point, bus, star and hub!
