5 .4 Connection HART standard
The following illustrations show in a simplified way the use of
VEGADIS
62 in conjunction with a HART sensor. The HART
communication resistance in the signal cable is always required for a
low impedance power supply. It is absolutely necessary to install it
between voltage supply and the VEGADIS 62.
Note:
If the instrument is powered via a VEGAMET signal conditioning
instrument, then the communication resistor is already included in the
signal conditioning instrument. A communication resistor in the signal
cable must not be installed.
