The
BA484DF-P Fieldbus Display is an intrinsically safe instrument that
can display up to eight fieldbus process variables. Eleven
selectable standard screen formats contain one, two, three, four or
eight variables, with units of measurement, tag descriptions and
bargraphs on some screens.
Powered by the fieldbus the BA484DF-P
only requires a 2-wire connection, no additional power supply Zener
barriers or galvanic isolators are required. The high contrast 86 x
45mm liquid crystal display incorporates a green backlight enabling
the display to be read in all lighting conditions from full sunlight
to total darkness.
Simple commissioning results from the
use of standard display formats. Apart from loading the BA484DF-P
configuration files onto the system host and selecting the fieldbus
variables to be displayed, no programming is re-quired.
Configuration of the BA484DF-P Fieldbus Display is performed via the
fieldbus and the instrument front panel push buttons.
ATEX, FM and IECEx intrinsic safety
certification allows the BABA484DF-P to be installed in gas and dust
hazardous areas. The two fieldbus terminals comply with the Fieldbus
Intrinsic Safety Concept (FISCO) simplifying system design and
documentation, although connection to non-FISCO intrinsically safe
systems is possible using the entity concept. This allows a
BA484DF-P display to be directly connected to almost any hazardous
fieldbus segment, provided that the segment can supply the 25mA
consumed by the display.
Six
optional local alarm outputs may be linked to any of the displayed
variables. Each isolated single pole solid state output may be
conditioned as a combined high and low alarm, or as just a high or
low alarm. All the outputs comply with the requirements for simple
apparatus allowing them to switch any certified intrinsically safe
load such as a sounder, lamp or solenoid valve. Alarm configuration
and the alarm set point adjustment is performed via the BA484DF-P
front panel push buttons, as the local alarms are not accessible
from the fieldbus system host.
The four push buttons on the front of
the instrument may be used for returning operator acknowledgments or
controls to the fieldbus host. If larger industrial switches are
required for these operator controls, up to six external push
buttons may be connected to the BA484DF-P. When the external
switches are activated, the front panel push buttons may be disabled
or operated in parallel with the external switches.
Comprehensive documentation includes
a PROFIBUS Interface Guide.
For panel mounting applications see
the BA488CF-P datasheet. This instrument has a similar electrical
specification but is housed in a 144 x 72 panel mounting enclosure.
Please specify if Certification
Documents, Alarms, Tag Strip, Tag Plate or Pipe Mounting Kit
BA392D/BA393 are required when ordering
