• The 4000x220.x.SE range is our largest range of weatherproofed digital clocks for outdoor or demanding environmental applications and offers a choice of ultra-bright red, white or yellow/amber digits.
• These clocks have robust weatherproof, IP65 rated corrosion-resistant enclosures with surface mounting, suspended and pole mounting options.
• This range of digital clocks has an exceptional performance record in outdoor applications and have London Transport and British Rail (PA05/03968) approvals. Typical applications include railway and other transportation systems, large public areas and manufacturing and storage facilities.
• These clocks will also operate as a multi-option stopwatch or as a programmable countdown timer.
• The 12 or 24-hour time display has 220mm (8.7") high digits for hours and minutes with 170mm (6.7") for seconds.
• You can select a display of time only, alternating time and temperature (requires extra cost temperature sensor) or alternating time and date.
• We include an RC100 handset for remote time-setting, stopwatch control, operating mode and special function selection.

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 digital clocks have time digits freely switchable between the display of time-of-day and the display of multifunction stopwatch or countdown time.
• The standard IR handset controls the stopwatch and countdown timer functions.
• The stopwatch functions on E and NE versions may also be controlled with an optional 496E dedicated switch panel or by external user-supplied voltage free contacts.
