DK Series Digital Clocks

»LED Digital Clock
The clock displays simultaneously an information about time and date. The date information can be displayed in one of 16 languages. One single display unit can be selected to alternate between 3 different languages.«

The Clock

display of time (either 12 or 24-hours time cycle), in either a four-digit form (HH:MM) or six-digit form (HH:MM^SS)
display of day of week – 3 characters display of month – 8 characters
temperature indication (if a temperature sensor is connected) in °C or °F, possibility of displaying one or two temperatures (two temperature sensors), and description
possibility of alternating display between date and temperature, with adjustable period of displaying the corresponding data
possibility of setting up the time zone, the display can cycle between up to five different places and display actual time and city name

Stopwatch

counting upwards from zero, up to 24 hours
counting downwards from a specified value, with stop at zero, with automatic restart or counting into minus values
display of intermediate time values, “freezing“ of display, cumulated intermediate time
counting in steps of 1 minute, 1 second or 1/100 seconds
operation via keyboard or remote IR controller
possibility to connect another display unit
possibility of parallel switching over into the time/date or temperature display mode

Basic properties

digits of 57 mm height, which corresponds to readability distance of 25 m
the letters 30 mm high
digits in red or green colour
manual or automatic adjustment of the display brightness
anti-glare front side cover, made of plexi-glass, which prevents the occurrence of reflections and improves the readability
single- or double-sided execution, for wall mounting (only single-sided clocks), ceiling suspension or wall bracket mounting
structural depth of 39/78 mm for clocks of single-/double-sided design, respectively
clock frame made of anodized aluminium profiles in black or silver colour any RAL colour tone or imitation of various materials (wood, marble) on request
adjustment of clock parameters using two pushbuttons on the upper side of the clock frame, or through remote controller
protection degree IP 54 optionally
digits in blue or yellow colour on request

Synchronization

autonomous operation with internal quartz time base (automatic seasonal time change) or with external DCF 77 radio time code receiver (DCF 450, GPS 4500)
slave clock operation with synchronization by polarized minute-impulses (24 V). Alternatively self-setting operation by MOBALine code. Optional available is the synchronization by RS 232, RS 485, IRIG-B or NTP (LAN)

Dimensions

removable rear cover, serving also as an anchor plate. The cover incorporates terminal board and provides for an easy assembly in two steps
ceiling suspension pieces in various lengths (5; 10; 30; 50 cm), according to the clock type
