Description
Files:
DD files allow the user’s handheld HART
communicator to fully configure the TTFM 6.1 Pulsar
Measurement provides DD files for the Emerson 475
Communicator. The files are included in the USB
drive provided with your TTFM 6.1 meter. You may
also request the files from Pulsar Measurement by
calling or emailing us at
.
Warning:
The TTFM 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
TTFM 6.1 is connected with a load resistor (230Ω to
600Ω), the HART communicator can be connected
on the loop in order to communicate.
