HART® (Highway Addressable Remote Transducer) Protocol Information:
HART Version: 7.0
Device Description Files: DD files allow the user’s handheld HART communicator to fully configure
the DFM 6.1. Pulsar Measurement provides DD files for the Emerson 475
Communicator. The files are included in the USB drive provided with your
DFM 6.1 meter. You may also request the files from Pulsar Measurement
by calling or emailing us at info@pulsarmeasurement.com. Warning: The
DFM 6.1 and associated DDs are pending certification from the
Fieldcomm Group.
Connections: HART Protocol uses a digital signal superimposed on the 4-20mA output.
When the 4-20mA output of the DFM 6.1 is connected with a load resistor
(230Ω to 600Ω), the HART communicator can be connected on the loop
in order to communicate.
