ATEX approved variable Profibus PA indicators
23 August 2010
Beka associates have introduced a range of cost effective eight variable Profibus PA indicators with 20mm high digits and a 31 segment bargraph, models include field and panel mounting, intrinsically safe, Type n and safe area indicators.
ATEX approved variable Profibus PA indicators
Each indicator may be configured as a fieldbus Listener or as a Node. When used as a Listener the indicator 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 push buttons. As a fieldbus Node configuration is via the fieldbus host, but the indicator’s fieldbus address may be entered via the instrument’s push buttons, which may also be used to return operator acknowledgements to the host.
The intrinsically safe models have ATEX, IECEx, FM and cFM approvals; the Type n indicator has ATEX and IECEx approval permitting installation in Zone 2 without an intrinsically safe segment isolator.
