4200x.057 Digital Clocks with 57mm digits

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 multifunction stopwatch or countdown time.
• The standard RC100 IR handset controls the stopwatch and countdown timer functions.
• You can also control the stopwatch functions of E and NE versions with an optional 496E dedicated switch panel or by external user-supplied voltage free contacts.
• Multiple N or NE versions of 4000 series clocks may be operated in Network Stopwatch Mode to provide a remote readout of stopwatch or timer counts.

496E switch panel – features:

• 1G plate size 86mm x 86mm with IP65 rated sealed switches.
• We supply the 496E panel with a 5m three core captive cable interconnection to the clock. You can extend the interconnection distance up to 20m using a 7/0.2 (0.22mm2) screened cable. Please contacttechnical support for longer interconnection distances.
• Please note that you must use either the RC100 infrared remote control or the rear-mounted clock setting switches for setting the clock time or the clock and stopwatch operating modes. You cannot use the 496E panel for time or function setting.
