3.4.8 Typical installations
System with devices connected to a Rosemount 2410 on a single tank
The example in Figure 3-7 illustrates a system with daisy-chained field devices on a single
tank. Terminators are installed at both ends of the fieldbus segment as required in a
FOUNDATION
™
Fieldbus system. In this example the terminators are enabled in the
Rosemount 2410 Tank Hub and a field device (Rosemount 2240S) at the end of the
network segment.
In addition to the field instruments on the Tankbus, Figure 3-7 illustrates how an
instrument such as a pressure transmitter can be connected to the intrinsically safe 4 -20
mA analog input of the Rosemount 2410 Tank Hub.

F. Rosemount 5900S Radar Level Gauge
G. Rosemount 2240S Multi-input Temperature Transmitter
H. Built-in terminator enabled on the last device
I. Tankbus length up to 1000 meter depending on number of devices and cable type
The Rosemount 2410 Tank Hub has a built-in terminator and intrinsically safe power
supply with integrated power conditioner. The maximum distance between the
Rosemount 2410 Tank Hub and the field devices depends on the number of devices
connected to the Tankbus and cable type.
Maximum number of HART Slave devices:
• Passive current loop: 5
• Active current loop: 3
