  • The 4000x.220 commercial and industrial digital clock range are our largest digital clocks for indoor applications and are readable at a distance of up to 100m (300 ft).
  • Typical applications include large public and commercial spaces, sports halls, factories and warehouses.
  • The range of case and mounting styles and operational options ensure that these clocks are suitable for many specialised applications.
  • These clocks will also operate as a multi-option stopwatch or as a programmable countdown timer.
  • The 12 or 24-hour clock face uses ultra-reliable, 220mm (8.7") high dot matrix characters for hours and minutes with 170mm (6.7") characters for seconds. You can choose daylight visible red, white or yellow/amber digits.
  • You can select to show 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.
  • 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, 24 or 48V DC 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.
