  • The Wharton 4000SE range of outdoor digital clocks with robust IP65 (NEMA 4X equivalent) rated weatherproof cases are a proven design for use in industrial and commercial outdoor applications and where protection from high humidity conditions is required.
  • 4000SE series digital clocks are ideal for use in air, rail and road transportation systems in addition to general industrial and commercial installations. The range is approved for London Underground applications and also has Network Rail Infrastructure approval (PA05/03968).
  • These clocks have been designed to provide an illuminated and highly visible display of time, time and date or time and temperature under virtually every ambient lighting condition. They are designed to operate without maintenance over an extended operating life with many previous models still in service more than 15 years after first supply.

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

  • Ultra-reliable, 12 or 24-hour time display with four or six-digit colour choice. Select alternating time and date or time, date and temperature (requires optional 406 temperature sensor).
  • E, N and NE versions can be used in stand-alone applications using their internal time references.
  • E and NE versions have rear connections to enable time synchronisation using one of an extensive selection of time code protocols from a Wharton 5000 series master clock or suitable third party time reference.
  • You can synchronise E and NE individual outdoor digital clocks to a 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 calendar clocks have time digits freely switchable between the display of time-of-day and the display of multifunction stopwatch or countdown time.
  • You can control the stopwatch and countdown timer functions by the IR handset supplied, by 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 on stopwatch & countdown timer operation.
  • The high-quality, robust weatherproof clock enclosure is manufactured from steel specially treated to resist corrosion and supplied with brackets for wall mounting and has a painted finish with a choice of colours.
