現(xiàn)場總線段之間也有電流隔離，從而防止多段接地故導致多段故障，每個段都有自己的現(xiàn)場總線功率調(diào)節(jié)器和電流限制。當安裝單個或幾余F80x模塊時，現(xiàn)場總線段的終端自動保持。AnF809F-Plus診斷模塊可選擇安裝在載體上，自動收和分發(fā)八個現(xiàn)場總線段的診斷信息。通過將F809FPIus作為現(xiàn)場總線設備分配給1段或8段供電段，或通過單獨的現(xiàn)場總線段，可在Foxborocontrol系統(tǒng)中查看測量參數(shù)，基板上提供了獨立段的連接，

There is also current isolation between the fieldbus segments to prevent multiple ground faults, each with its own fieldbus power regulator and current limit. When one or more F80x modules are installed, the terminal of the fieldbus segment is automatically held. The AnF809F-Plus diagnostic module can be optionally mounted on a carrier to automatically receive and distribute diagnostic information across eight fieldbus segments. The measurement parameters can be viewed in the Foxborocontrol system by assigning the F809FPIus as a fieldbus device to a 1 – or 8-segment power supply segment, or through a separate fieldbus segment. Connections for individual segments are provided on the substrate, see F809F-Plus product specifications for more information. a few more 24V DC(nominal) input power supplies can be connected to the F810 chassis using the Foxboro l/a standard amplifier connector. The F80x power supply and F809F-Pus fieldbus diagnostic module can be powered from the same power supply, or, for devices where the standard Foxboro power supply does not provide sufficient current capacity, an external 24V DC power supply can be connected. Field wiring can be connected using a pluggable screw terminal (F810-PS) or a pluggable clip terminal (F810-PC).
