Rosemount Model 3144 and 3244MV Smart Temperature Transmitters
B-4
CONNECTIONS AND
HARDWARE
The Model 275 HART Communicator can interface with a transmitter
from the control room, the instrument site, or any wiring termination
point in the loop through the rear connection panel as shown in
Figure B-2. To communicate, connect the communicator in parallel with
the instrument or load resistor. The connections are non-polarized. Do
not make connections to the serial port or NiCad recharger jack in an
explosive atmosphere. Before connecting the communicator in an
explosive atmosphere, make sure the instruments in the loop are
installed in accordance with intrinsically safe or non-incendive field
wiring practices.
