3.1.3.3 Fieldbus Connection

Fieldbus Controller 750-841
Hardware
Connection to the fieldbus is by a RJ45 connector. The RJ45 socket on the
fieldbus controller is wired per the 100BaseTX standard. The specification for
the connecting cable is a twisted pair cable of Category 5. Cables of type S-
UTP (Screened-Unshielded Twisted Pair) and STP (Shielded Twisted Pair)
with a maximum segment length of 100 meters may be used.
The RJ45 socket is physically lowered for the controller to fit in an 80 mm
high switch box once connected.
The electrical isolation between the fieldbus system and the electronics is
achieved by DC/DC converters and optocouplers in the fieldbus interface.
Fig. 3.1-3: RJ45-Connector and RJ45 Connector Configuration
The operating condition of the controller or the node is displayed with the help
of illuminated indicators in the form of light-emitting diodes (LEDs).
The LED information is routed to the top of the case by light fibres. In some
cases, these are multi-colored (red/green or red/green/orange).
