Specificaties:
Display
User selectable for 12 or 24 hour operation. Bright red, green, yellow or blue,
colour matched and brightness selected LED characters. Ultra bright, daylight
visible red or yellow/amber LEDs are available for SE models used for outdoor
or very high ambient light conditions. The display brightness can be manually
pre-set or controlled automatically.
The following optional display modes may be selected by the user:
alternating time-temperature
alternating time - date
alternating temperature - time - date
note. temperature display requires optional 406 temperature sensor
when the digital clock is displaying time and temperature or time and date the
interval between display changes is user adjustable.
Internal clock
The internal time base is pre-programmed for leap years and the local
automatic seasonal time changes can be programmed by the user.
Case construction Clock cases are finished in high quality brushed black or silver anodising and
manufactured from aluminium extrusion and sheet. Digital Clock enclosures can
also be supplied painted to any standard RAL colour as an extra cost option.
Ten different case installation options are available for all applications.
Power supply
The 400A series LED digital clock range can be supplied for operation from 110
or 230v 50/60 Hz ac supplies or from 12v, 24v or 48v dc supplies at extra cost.
The operational location and supply voltage should be specified at time of order
so that the unit is supplied with the correct mains connection.
stopwatch operation
simple stopwatchoperation using
external switches
The digital clock can be user programmed to function as a
simple stopwatch controlled by two user supplied, voltage free,
switch contacts connected to screw terminals on the rear of
the clock or internally in the case of .SE models.
The two switches function as stop/start and hold/reset
controls. The display may be programmed to show a stopwatch
count in hours, minutes and seconds (hours and minutes for
420A model) or minutes, seconds and 1/100 seconds (minutes
and seconds for 420A model).
stopwatchoperation using 496A
control panel
The 496A stopwatch control panel provides a
convenient means of operating a 401A, 420A
or 490A digital clock as a simple stopwatch.
The 496A panel is fitted with sealed switches
and is intended for flush mounting.
The panel is also available mounted in a handheld case or in an enclosure suitable for wall
mounting.
programmablestopwatchoperation
using 402A control panel
The 402A stopwatch control panel enables
401A, 420A or 490A series LED digital clocks
to be used both as multi-function
programmable up/down stopwatches and as
time-of-day clocks with the display freely
switchable between time-of-day and
stopwatch time. The following counting modes
are programmable:

up from zero

count down from a pre-programmed
start-time to stop at zero.

count down from a pre-programmed
start-time and then up through zero.

continuously count down to zero with
automatic restart from a preprogrammed start time.

timekeeping & synchronisation
401x, 420x,and 490x series digital clocks will operate as stand-alone clocks or may be
synchronised from a wide range of external time references.
Stand-alone operation
When used in stand-alone configuration the digital wall clock
maintains time keeping from a high stability internal crystal
controlled time base. The clock can be user programmed for
the appropriate local automatic seasonal time-change and is
pre-programmed for leap-years.

environment
Power supply
401x, 420x and 490x digital wall clocks will operate from a 110v - 240v
50/60Hz ac power supply depending on order specification. The power
consumption is ‹0.2A @230v.
operation from 24v DC supplies is available at extra cost.
