»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:MMSS)
- 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
