4000x.057 LED wall clocks with 57mm (2.3") digits

• Our 4000N.057 range of multi-function digital clocks and stopwatches are available with and without seconds digits and offer proven extended operational life in time and reliability critical professional applications.
• Typical applications range from classrooms to operating theatres, control rooms, reception areas and manufacturing and research process timekeeping.
• You can choose from a wide range of case types and time synchronisation options.
• The clock will operate as a multi-function stopwatch or programmable count-down timer that can be controlled either by the included IR handset or via user-supplied voltage free contacts.
• The 12 or 24-hour time display uses ultra-reliable, colour matched 57mm (2.3") digits for hours, minutes and seconds. You have a choice of blue, green, red or yellow/amber digits.
• You can select a display of time only, alternating time and temperature (requires extra cost temperature sensor) or alternating time and date.

All Wharton digital clocks have many user-selected modes of operation:

• E and NE versions can be used in stand-alone applications using their internal time references.
• Every standard digital clock has rear connections to enable time synchronisation using one of a wide selection of time code protocols from a Wharton 5000 series master clock or suitable third party time reference.
• You can synchronise individual clocks with a precise satellite-based atomic time reference via a control message from a Wharton 488HS series GPS or GLONASS time signal receiver.
• N and NE versions can be controlled and synchronised to time via their 10/100Base-t Ethernet NTP connection to your existing network with accurate time information provided by a local or internet time server for simple, low-cost installation and control.

Stopwatch operation

• Wharton 4000 series clocks have time digits freely switchable between the display of time-of-day and the display of multifunction stopwatch or countdown time.
• The IR handset controls the stopwatch and countdown timer functions. These functions can also be controlled with an optional dedicated switch panel or by user-supplied voltage free contacts.
• The following stopwatch and countdown timer functions are user-programmable:
  • Stopwatch display modes
  • Stopwatch display resolution
  • Stopwatch count direction
  • Stop/start and hold switch actions
  • Countdown start count
  • Using external, voltage-free, switch contacts - E and NE versions only
  • Network stopwatch mode - network versions only
• Further information about stopwatch & countdown timer operation

• The high-quality clock enclosures have a silver or black finish. Alternative colours or finishes are available at additional cost.
• Base model clocks are suitable for freestanding or wall mounting using the multi-angled brackets supplied. Mounting options include cases for flush wall mounting and single or double-sided clocks with mounting supports for ceiling suspension.
• 110-230V AC, 12 or 24V DC or PoE (Power over Ethernet) power supply options.
• All Wharton digital clock products are designed, manufactured and tested to International Quality and Performance Standards.
• Unrivalled free product lifetime technical support with unlimited advice and information to the original user for the life of the digital clock. Many previous models are still in service more than 15 years after first supply.
