The ATC Diversified Electronics
division of Marsh Bellofram Corp.'s
405A series is an industrial timer family with on-delay
instantaneous relay function, designed for daily-use OEM and control package
timing applications. The Marsh Bellofram 405A series features six individual
timing ranges within a single unit, packaged within a 48mm2 DIN
housing. The housing is watertight when panel mounted with an 8-pin round
(octal) socket. A selectable on-delay/interval timing mode version is also
available. The timer operates from 24-240V ac or 24V dc power, and features a
large and easy-to-read display dial with decimal points. Output contacts are
rated 10A 120/240V ac and 30V dc. Mode and range select switches are located on
the side of the unit, so that when panel mounted, they are no operator
accessible, a tamperproof feature that prevents unauthorized or hazardous changes
to the timing mode and range. A special LED indicator provides a method of
cycle progress indication. Units are
CE marked and UL-pending, as well as CSA and FM approved, facilitating their
use across a variety of industrial environments.
A bold, gold, open-air coupe may not be the ticket to automotive nirvana for every consumer, but Lexus’ LF-C2 concept car certainly turned heads at the recent Los Angeles Auto Show. What’s more, it may provide a glimpse of the luxury automaker’s future.
The complexity of diesel engines means optimizing their performance requires a large amount of experimentation. Computational fluid dynamics (CFD) is a very useful and intuitive tool in this, and cold flow analysis using CFD is an ideal approach to study the flow characteristics without going into the details of chemical reactions occurring during the combustion.
