The OBT has a compact plastic housing. It is suitable for mounting on a DIN rail or for wall mounting with a mounting plate with the aid of two holes drilled right through.
The OBT has the following connections:
9-pin sub-D socket for connecting the PROFIBUS DP node such as programming device (PG), PC, operator panel (OP), S7-300 or nodes without integral optics, e.g. ET 200S or PROFIBUS DP components from other suppliers or a PROFIBUS DP-RS 485 segment.
Two optical interfaces for the connection of plastic and PCF fiber-optic cables with Simplex connectors (connection to CP 342-5 FO, CP 5613 FO, IM 153-2 FO, IM 467 FO or to ET 200 with integrated optics)
