Rosemount 3300 Series

Level-4

System Integration

INPUTS / OUTPUTS

The 3300 Series transmitter uses the same two wires

for both power supply and output signal

(loop-powered).

See page Level-16 for more information about power

supply.

Measurement data is transmitted as an analog

4-20 mA signal with a superimposed digital HART

signal. The HART

signal can be used in a multidrop

mode.

As an option, the 3300 Series is available with

Modbus output (requires separate power supply).

However, HART

communication is used for

configuration.

By sending the digital HART

signal to the optional

HART

Tri-loop, it is possible to have up to three

additional 4-20 mA analog signals.

See the Rosemount 333 HART
