Rosemount 2410
Section 3. Installation
3.4.13 Intrinsically Safe
Terminal Block
The Intrinsically safe side of the Rosemount 2410 Tank Hub connects to the
Tankbus which communicates with field devices on the tank.

side
Tankbus
The devices on the tank communicates with the Rosemount 2410 via the
intrinsically safe Tankbus. All field devices in the Raptor system have built-in
communication modems for FISCO F
OUNDATION fieldbus (FF) communication
and will automatically communicate with the 2410 when connected to the
Tankbus.
Optional Secondary Bus
In addition to the Tankbus an optional intrinsically safe bus is available for
communication with devices not compatible with F
OUNDATION fieldbus. It
allows you to connect devices for intrinsically safe HART 4-20 mA analog
input/output communication.
