OBT - Optical Bus Terminal
Use the advantages of optical data transmission for existing DP devices:
Using the OBT (Optical Bus Terminal), a PROFIBUS station without integrated optical interface is connected to an optical line with PROFIBUS stations.
A connection is made to the RS485 interface of the OBT via an RS485 interface and a connecting cable terminated at both ends. The OBT is integrated into the optical line using two optical interfaces.
The following optical transmission media can be connected to the OBT:
Investment protection by connecting existing devices or an RS485 segment with an electrical interface to the optical PROFIBUS
“Socket” for the connection of mobile devices (e.g. programming devices) without interruption in the bus
Time is saved thanks to easy and quick installation without the need for special tools
