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 (RL) of 250 Ω within the loop in order to function properly, see diagrams below.
