4200x.057.SEP dust and water resistant indoor digital wall clocks with 57mm (2.3″) digits and robust IP65 rated cases
Our dust and water resistant range of indoor digital clocks offers a choice of red, green, yellow and blue digits and has robust, IP65 rated corrosion-resistant enclosures with surface mounted cases.
Designed for extended life in adverse environmental conditions these clocks are suitable for special environments such as food manufacture areas where they will be washed down or particularly dusty environments.
Description
- Our dust and water resistant range of indoor digital clocks offers a choice of red, green, yellow and blue digits and has robust, IP65 rated corrosion-resistant enclosures with surface mounted cases.
- Designed for extended life in adverse environmental conditions these clocks are suitable for special environments such as food manufacture areas where they will be washed down or particularly dusty environments.
- These clocks will also operate as a multi-option stopwatch or as a programmable countdown timer. The 12 or 24-hour time display has ultra-reliable, 57mm (2.3″) high digits for hours and minutes indication.
- Each clock can display 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.
Operation
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 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
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 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 function
- Stopwatch display modes
- Stopwatch display resolution
- Stopwatch count direction
- Stop/start and hold switch actions
- Countdown start count

Installation
- The robust dust and water resistant enclosure is IP65 rated, manufactured from steel specially treated to resist corrosion and supplied with brackets for wall mounting.
- The clock enclosure has a High-quality paint finish to RAL 7001 50% gloss but you can specify any standard RAl colour as an extra cost option.
- 110-230V AC, 12 or 24V DC or PoE (Power over Ethernet) power supply options.
- All Wharton digital clock products are designed, manufactured and tested to International Quality and Performance Standards. The range is approved for London Underground applications and also has Network Rail Infrastructure approval (PA05/03968).
- 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.
