10/100Base-t Ethernet interface.
Automatic synchronisation with remote NTP network timeservers across a TCP/IP Ethernet network
Remote configuration, management and software update across the Ethernet TCP/IP network using Wharton cMon software
Fully automatic network configuration support when used with DHCP server supporting option 42
100-240V 50-60Hz AC mains and 24V DC power options available.
User programmable time zone location names  
External synchronisation modes available as standard: version
Wharton w482 multi time zone time code
MB serial and MobaLine time codes.
Automatic synchronisation with remote NTP network timeservers across a TCP/IP Ethernet network
The clock may be synchronized using one of the following optional time code receivers: version
  option code N NIL
DCF77 484.03
MSF 484.02
Local synchronisation output : version
The local synchronisation output enables the clock to act as a master to up to ten other 47xx series time zone display clocks using a simple single cable pair.

4000 series clocks are manufactured from aluminum extrusion and sheet in a range of case styles and high quality finishes to suit the most demanding applications.

  • Operating temperature: 0-50°
  • Relative Humidity: 0% to 95% (non-condensing.)
  • Altitude: 0 to 3,000m
Timing accuracy
  • Each clock has a high quality quartz crystal oscillator - unsynchronised accuracy: 0.1 sec/day @ 20-25°C
  • When synchronised via an NTP/SNTP timeserver the clock is typically synchronised within 1-10 milliseconds of master clock timebase depending on network delay and jitter. (N and NE versions only)
  • MSF or DCF synchronisation: ±20mS of UTC when synchronised via an 484.02 (MSF) 484.03 (DCF) radio time code receiver (E and NE clock versions only).
  • GPS/GLONASS synchronisation: ±5mS of UTC when the clock is synchronised via a488.HS3-GPS or 488.HS3-GLONASS receiver.
