Note
For flameproof/explosion-proof installations, the diagram is only valid if the HART load
resistance is at the + side and if the - side is grounded. Otherwise, the load resistance value is
limited to 435 :.
Note
Rosemount 5400 Series Transmitters with flameproof/explosion-proof output have a built-in
barrier; no external barrier needed.
