1. Application
Digital clocks of the DLZ type are used to display current time indoors. They can also display the
current date and, in cooperation with the P8 transducer, the temperature and humidity. The communi-
cation interface of the clock allows for easy configuration of the clock, and the second inbuilt interface
RS8 makes it possible to cooperate with the temperature and humidity transducer. The transducer
output values can be read by means of the user interface.
The DLZ clocks are equipped with a programmed brightness function to allow for energy savings when
the clock does not need to work, or when full brightness could dazzle the user.
The DLZ clocks are used wherever there is a need for the current time, date, temperature and humidity
to be displayed.
It is possible to adjust the clock in accordance with the customer alignments.
