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.
