HART communication
The Rosemount 5300 Series transmitter operates with a power supply ranging
from 16 - 42.4 Vdc (16 - 30 Vdc in IS applications, 20-42.4 Vdc in Explosion-proof /
Flameproof applications and in Non-Sparking / Energy Limited applications).
All configuration tools for HART communication, such as the Field Communicator
and Rosemount Radar Master, require a minimum load resistance (R
L
) of 250
within the loop in order to function properly, see diagrams below.
Non-intrinsically safe power supply
NOTE:
Rosemount 5300 Series Transmitters with Flameproof/Explosion-proof output have a
built-in barrier; no external barrier needed.
