BA684DF-P PROFIBUS PA Fieldbus display 8 variables Standard display formats: 1, 2, 3, 4 or 8 variables some with bargraphs. Fieldbus Terminator Power Supply & Segment Coupler u ompatible with most C Field Device system hosts. Field Device u High contrast display The BA684DF-P Fieldbus Display is a general purpose 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 BA684DF-P only requires a 2-wire connection, no additional power supply is 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 BA684DF-P configuration files onto the system host and selecting the fieldbus variables to be displayed, no programming is required. Configuration of the BA684DF-P Fieldbus Display is performed via the fieldbus and the instrument front panel push buttons; simple menus enable the required standard display format to be selected and the units of measurement and tag information for each variable to be entered. 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. Each output can switch any low power load such as a sounder, lamp or solenoid valve. Alarm configuration and the alarm set point adjustment is performed via the BA684DF-P front panel push buttons, as the local alarms are not accessible from the fieldbus system host. BA684DF-P applications vary from a simple single variable display using a standard format, to providing an operator interface with a custom display and control inputs via external buttons. 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 BA684DF-P. When the external switches are activated, the front panel push buttons may be disabled or operated in parallel with the external switches. with backlight. buttons & six optional local alarm outputs. u P66 field mounting I GRP enclosure. Comprehensive documentation includes a PROFIBUS Interface Guide. For panel mounting applications see the BA688CF-P datasheet. This instrument has a similar electrical specification but is housed in a 144 x 72 panel mounting enclosure. If flammable atmospheres are present the intrinsically safe BA484DF-P fieldbus display should be used. For FOUNDATION™ fieldbus systems, please see the datasheet for the equivalent BA684DF-F fieldbus display. BEKA associates Ltd. Old Charlton Rd. Hitchin, Hertfordshire, SG5 2DA, U.K. Tel.
