4.9 FOUNDATION fieldbus
4.9.1 Power requirements
Terminals in the transmitter housing provide connections for signal wiring.
The Rosemount 5400 transmitter is powered over F
OUNDATION fieldbus with standard fieldbus
power supplies.
The transmitter operates with the following power supplies:
The Rosemount 5400 Series 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
