Description

ZA5-L PoE+ PrestigeLine clocks have a housing made of polycarbonate, which is resistant to UV radiation and has a high mechanical strength. By using the thermo-moulded housing and a rear sealing layer, the device, when properly assembled, meets theIP66 tightness requirements.

• 5 cm height LED digits
• NTP Ethernet Time Synchronisation
• Web Browser or IR Remote Control
• Supports Daylight Savings Time
• Automatic Brightness Control
• PoE for easy installation
• IP 66 Rated for outdoor installation

The clock supports the activation of the automatic time change from the standard time to the daylight saving time and from the daylight saving time to the standard time (DST – Daylight Saving Time).

Automatic brightness control based on the measurement of ambient light by the sensor ensures real adjustment of the display brightness to the current lightning conditions of the surroundings. In addition to the automatic brightness control based on the sensor, there is a possibility to manually select and lock one of 10 brightness levels.

NTP synchronization advantages:

– provides precise time synchronization with the NTP servers
– possibility of simultaneous synchronization of many clocks from the same server
– operation of five different time servers (1 primary and 4 alternative) provides reliable synchronization.
– changing the time server from the primary to an alternative one is carried out automatically when a failure is detected.

The NTP time synchronization is carried out via the Ethernet (the interface is included in the standard equipment of every clock). The synchronization may be executed:
– from your own local time server – the Internet access is not required
– from a public remote time server – the Internet access is required

Function of the local NTP time server

Every clock of ZAS/ZBS series may be a central clock (MASTER) which, in the LAN, will provide the  time source for other clocks (Slave). In consequence, it is easy to create a clock system in which the  central clock can receive time from: a public NTP server or its own internal clock.
Providing synchronized time to all clocks guarantees that everybody uses the same time source. It is extremely important for workplaces, production halls, schools, stations, platforms, etc.
