A.2 Communication/display/configuration
specifications
A.2.1 Tankbus
The intrinsically safe side of the Rosemount 2410 connects to the Tankbus, which
communicates with the field devices on the tank using FOUNDATION
™
Fieldbus.
A.2.2 Fieldbus
Rosemount 2410 communicates with a Rosemount 2460 System Hub, Rosemount
TankMaster, or a host via the supported communication protocols for the primary and
secondary fieldbus.
Primary fieldbus:
TRL2 Modbus, RS485 Modbus, Analog output/input 4-20 mA/HART
or Enraf
®
Secondary
fieldbus:
TRL2 Modbus, Analog output/input 4-20 mA/HART, WirelessHART
®
or other vendors’ protocols, such as Enraf, L&J Tankway and Sakura
MDP/V1
For combination guidance, see Table A-1 and Table A-2.
A.2.3
Relay outputs
SIL 3 relay
output:
One certified SIL 3 relay is available for overfill prevention. This non-
intrinsically safe solid state relay is closed/energized during normal
operation.
Maximum voltage and current: 260 Vac/Vdc, 80 mA single pole
Relay outputs
(SIL 2 or non-
SIL):
Maximum two relays, controlled by 10 independent virtual relay
functions, which can be configured for different tanks and process
variables. The two non-intrinsically safe solid state relays are user
configurable for normally energized or de-energized operation.
Maximum voltage and current: 350 Vac/Vdc, 80 mA single pole
For combination guidance, see Table A-1 and Table A-2.
A.2.4
Analog input/output
The tank hub supports analog output and input 4-20 mA/HART, active or passive, IS or
non-IS. The analog output is available as certified SIL 2.
Analog input
Maximum number of input channels: 1
Input Current range: 0-23 mA
Configurable Min and Max alarm limits.
