47x series world clocks and world time clocks are designed and manufactured to meet the requirements of the most demanding, prestigious and reliability critical applications in dealing rooms, command, control and communications facilities, conference and reception areas.
Time, date and illuminated location information is displayed using ultra reliable, colour and brightness matched red, green, yellow or blue LED characters. 470 and 475 series units can display date information in one of over 20 different languages.
Every 47x series world clock is supplied with customer specified time zone location names. 47xA or 47xN models have white printed location names with optional interchangeable name-plates. 47xAIL30 or 47xNIL30 world clocks have 30mm (1.2”) high programmable illuminated location names and 47xAIL50 or 47xNIL50 units have 50mm (2”) high illuminated location names.
All 47x series world time clocks may be programmed using the IR handset supplied or by a PC via an RS232 serial connection. 47xN models may be programmed from a remote ethernet enabled pc.
47x series world clocks are designed for global use and will operate from a 100-250v 50/60Hz ac supply. The clocks are available in a range of high quality anodised or painted aluminum case styles with versions suitable for wall mounting, single or double sided ceiling suspension or flush mounting in a panel or a solid wall.
47x series world time clocks may be used as independent time zone displays pre-programmed for leap years, statutory time changes and time-offsets for almost every global time zone time change. They may be synchronised from optional GPS, DCF or MSF time signal receivers or be installed as part of a system controlled by time code from a central 4850 or 4860 series master clock. 47xN series units are synchronised via their 10/100Base-T ethernet interfaces.

timekeeping & synchronisation to top of page
47x series time zone clocks will operate either as stand-alone units or synchronized from an external time reference.
Stand-alone operation When used in stand-alone configuration the time zone clock maintains time keeping from a high precision internal crystal oscillator. The time zone clock is pre-programmed for leap-years, seasonal time changes and time-offsets for almost every global time zone.
GPS time sync. 47x series time zone clocks can be synchronised to highly accurate GPS time signals by the addition of a 488 series time code receiver sub-system.
DCF & MSF radio sync. 47x series time zone clocks can be synchronised to accurate DCF & MSF radio time code signals by the addition of a 484 series radio time code receiver.
w482 time code sync. The most popular method of controlling 47x series time zone clocks in system applications is via means of multi-zone w482 time code generated by a central 4850 or 4860 series master clock.
