1 Application Structure
The HRT-370 module is a HART signal Filter. When connecting
HRT-370 to a HART instrument, it splits the HART slave signal to
two channels, one keeps the original HART signal and another
filers the HART digital signal out to output a pure analog signal.
Therefore, users can make both HART and analog current data
collection and processing easier and more precise by applying
HRT-370 in the HART network.
