Safe area BA444NDF-P PROFIBUS PA Fieldbus indicator 8 variable Type n certified for use in Zones 2 and 22 Field Device Field Device The BA444NDF-P PROFIBUS Indicator is a Type n instrument that can display up to eight fieldbus process variables within a hazardous area. A numeric annunciator on the left hand side of the screen shows which variable is being displayed. This version of the indicator supports PROFIBUS PA protocol; for FOUNDATION™ fieldbus systems an alternative version is available - please see BA444NDF-F FOUNDATION™ fieldbus datasheet. Configuration as a fieldbus Node or Listener using the indicator’s front panel push buttons allows the instrument to be tailored to suit local requirements. When configured as a Listener the BA444NDF-P is not visible to the fieldbus host; may not be subject to a Node Licence Fee and is configured and controlled via the instrument’s front panel push buttons. As a fieldbus Node, the indicator is configured by the fieldbus host and the displayed variable is selected from the eight pre-configured variables using the indicator’s front panel up and down buttons. Powered by the fieldbus the BA444NDF-P only requires a 2-wire connection to the fieldbus segment, no additional power supply is required. Compatibility with most PROFIBUS hosts is assured by the use of eight Analogue Output and six Digital Input function blocks. The liquid crystal display has large 20mm high digits providing maximum contrast and a wide viewing angle, allowing the BA444NDF-P Profibus indicator to be read easily in most lighting conditions. The five digits, with four decimal points and a negative sign, may be configured to display any variable between -99999 and 99999. The 31 segment bargraph, which provides a bold analogue indication of the fieldbus variable may be conditioned to any starting or finishing values within the fieldbus variable’s range. The enclosure which is moulded in glass reinforced Polyester (GRP) has stainless steel fittings, silicone gaskets and an armoured glass window. Its robust construction provides IP66 protection which has been independently assessed by Intertek Testing Services. A separate terminal compartment allows the instrument to be installed and terminated Power «=> Supply & Host Segment Coupler without exposing the indicator electronics. To further simplify wiring and subsequent inspection, the terminal cable entries and clamping screws are forward facing. The indicator may also be mounted onto a vertical or horizontal pipe using one of the accessory kits. ATEX Type n and tD certification allows the BA444NDF-P to be installed in Zone 2 gas and Zone 22 dust hazardous areas. The two fieldbus terminals comply with the Fieldbus Non-incendive Concept FNICO simplifying system design and documentation. Separate entity input safety parameters also allow connection to most non-FNICO Type n systems. A BA444NDF-P may therefore be connected to almost any Type n fieldbus segment that can supply an additional 13mA to power the instrument. IECEx approval permits installation in the many countries already accepting international IECEx certificates. The approval incorporate FNICO certification and dust approval for use in Zone 22. Operator acknowledgements may be returned to the fieldbus host when the BA444NDF-P is configured as a fieldbus Node. Six Digital Input function blocks in the indicator which are supported by most Profibus hosts enable the status of the four front panel push buttons to be read. A Comprehensive PROFIBUS interface guide contains commissioning information for the BA444NDF-P. Copies may be requested from the BEKA sales office or downloaded from www.beka.co.uk Units of measurement and the instrument’s application or tag number can be economically marked onto the display escutcheon prior to despatch or after installation on-site. Alternatively, for customers who prefer a stainless steel label, the indicator can be supplied with a removable blank or custom etched stainless steel plate mounted on the front of the enclosure.
