Specifications
The DeltaV system supports the Single Port Fiber Switch and the Four
Port Fiber Switch. The Single Port Fiber Switch is an Ethernet switch with one
100BASE-FX port and four 10/100BASE-TX ports. The Four Port Fiber Switch is an
Ethernet switch with four 100BASE-FX ports and one 10/100BASE-TX port. The
switches can be mounted on a DIN rail and provide comprehensive LED
diagnostics. The switches can be installed in Zone 2 and provide connection to
Zone 1 components over the certified energy-limited fiber port. Primarily the
switches are the fiber port connection to the Zone 1 components; however, they
can be used for all Control Network applications. Refer to the
Installing Your DeltaV Zone 1 Intrinsically Safe Hardware
manual in Books Online for information on connecting to the
DeltaV Intrinsically Safe system.
