Chapter 2 Installation Instructions
Figure 53 - Connections for 120 Ω Resistor & Secondary Master
above shows the addition of the 120
Ω
resistor and HART Secondary
Master to the Two-wire Analog Input Field Loop Circuit shown in
.
The above circuit can be accomplished by connecting the secondary Master
and 120
Ω
resistor assembly to the 0 V terminal and required channel terminal
on the terminal block as shown in
below.
IMPORTANT
It is the responsibility of the Installation Engineer to ensure that
the HART secondary Master is correctly installed. information
regarding HART equipment may be obtained from the HART
website.
