1. APPLICATIONS
The DZ digital clock shows the date and time alternately. The quantity switching over is set arbitrarily.
The default value is equal 5 seconds.
These digital clocks are intended to be installed outside and inside shops, by production lines, in sto-
res, refrigeration plants, sports and commercial objects.
The DZ2 clock (digits of 200 mm high) ensures a good readout from 80 m distance. The DZ3 clock
(digits of 300 mm high) ensures a good readout from 120 m distance.
These clocks are offered with digits in 3 versions of colours: red, green and yellow.
DZ clocks co-operate with an external DCF receiver, atomic time standard. These clocks are synchro-
nized every now and again with the time standard.
They have additionally the RS-485 interface with MODBUS RTU protocol. This interface enables to set
the clock in case when the DCF signal is too weak and there is no possibility to synchronize the clock
with the time standard.
The luminosity of digits is programmed by the user taking into consideration the night-time.
