3.4.12 Wiring diagrams
The standard version of the Rosemount 5900S has a single intrinsically safe fieldbus input.
You may activate a built-in fieldbus 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 Rosemount Tank Gauging system.
Connector X3 is used for a fieldbus input/output cable shield connection (separated from
chassis ground).
Figure 3-30
connected to a Rosemount 2240S temperature transmitter. In this example the
termination is enabled in the temperature transmitter which is the last device on the
Tankbus (see Tankbus).
In case you prefer to connect the temperature transmitter to the tank hub, you may
"daisy-chain" the Rosemount 5900S to the temperature transmitter, and terminate the
Tankbus by a jumper in terminal X2 on the Rosemount 5900S terminal block.
