Rosemount 5900 Series
Section 3. Installation
3.4.11 Wiring Diagrams
The standard version of the Rosemount 5900 has a single intrinsically safe
fieldbus input. The 5900 has a built-in termination by short circuiting the X2
connector.
An intrinsically safe output on connector X4 can be used for “daisy-chain”
connection to other devices in a Raptor system.
Connector X3 is used for a fieldbus input/output cable shield connection
(separated from chassis ground).
Figure 3-22 illustrates a typical wiring diagram with a Rosemount 5900 level
gauge connected to a Rosemount 2240 multi-input temperature transmitter. In
this example the termination is enabled in the 2240 transmitter since this is
the last device on the Tankbus (see “The Raptor Tankbus” on page 3-41).
In case you prefer to connect the 2240 to the 2410 tank hub, you may
“daisy-chain” the 5900 to the 2240, and terminate the Tankbus by a jumper in
terminal X2 on the 5900 terminal block.
