System architecture
The Rosemount 5300 Series Radar Transmitter is loop-powered, and it uses the same two
wires for both power supply and output signal. The output is a 4-20 mA analog signal
superimposed with a digital HART
®
, F
OUNDATION
™
Fieldbus, or Modbus
®
signal.
By using the optional Rosemount 333 HART Tri-Loop
™
, the HART signal can convert up to
three additional 4-20 mA analog signals.
With the HART protocol multidrop configuration is possible. In this case, communication is
restricted to digital, since current is fixed to the 4 mA minimum value.
The transmitter can be connected to a Rosemount 751 Field Signal Indicator, or it can be
equipped with an integral display.
The transmitter can easily be configured using a Rosemount Field Communicator or a PC
with the Rosemount Radar Master software. Rosemount 5300 Series Transmitters can also
be configured with the AMS
™
Suite and DeltaV
™
software, and other tools supporting
Electronic Device Description Language (EDDL) functionality.

Note
For HART communication, a minimum load resistance of 250 Ohm within the loop is
required.
