  • These Ethernet-enabled digital clocks with optional PoE have one or two integral stopwatch displays within a single case and offer a wide range of specification options.
  • Custom units with 100 mm (4") digits are available.
  • You can specify blue, green, red or yellow characters.
  • We supply an RC100 handset for time-setting and unit configuration.
  • The stopwatch control options are the 496E control panel, external voltage-free contact pairs or the RC100 handset (first stopwatch only).
  • You can conect multiple remote secondary displays via your network.
  • Please enquire for custom units with temperature, humidity and tally displays.

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

  • 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.
  • This range of digital clocks with integeral stopwatch displays 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

  • Stopwatch and Countdown control options are:
    • Stopwatch One (all versions) - a 496E control panel, external voltage-free contact pairs or the RC100 handset.
    • Stopwatch Two (4012NE & 4202NE only) - a 496E control panel or external voltage-free contact pairs.
  • You can operate multiple 4011NE, 4012NE, 4201NE and 4202NE versions in Network Stopwatch Mode to provide a remote readout of stopwatch or timer counts.
496E stopwatch control panel

496E switch panel - features:

  • 1G plate size 86mm x 86mm with two 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 contact technical 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.

User-programmable stopwatch and countdown timer functions

  • Stopwatch display modes
  • Stopwatch display resolution
  • Stopwatch count direction
  • Stop/start and hold switch actions
  • Countdown start count
