4.10.1 Power requirements
Terminals in the transmitter housing provide connections for signal wiring.
The Rosemount 5400 is powered over F
OUNDATION Fieldbus with standard fieldbus power supplies.
The transmitter operates with the following power supplies:
The Rosemount 5400 with F
OUNDATION Fieldbus operates using a power supply ranging from 9-32 Vdc
(9-30 Vdc in IS applications, 16-32 Vdc in explosion-proof/flameproof applications, and 9-17.5 Vdc in
FISCO, IS applications).
Grounding
Signal wiring of the fieldbus segment cannot be grounded. Grounding out one of the signal wires will
shut down the entire fieldbus segment.
Shield wire ground
To protect the fieldbus segment from noise, grounding techniques for shield wire usually require a single
grounding point for shield wire to avoid creating a ground loop. The ground point is typically at the
power supply.
Approval type Power supply (Vdc)
IS 9 - 30
Explosion-proof/flameproof 16 - 32
None 9 - 32
