APPLICATION

Digital displays of DN type can be applied for the visualisation of es-

sential parameters in automation and measurement processes when

supervising the quality or working safety.

Information put in a visible place helps in the efficient work in industrial

communication, logistics, automation and control technology, and material

handling. These displays are destined to be installed in: industrial plants,

sports objects, trade buildings and communication areas.

The character height ensures a good visibility and reading from a long

distance, up to 120 m.

Digit heights:

DN1 - 100 mm; DN2 - 200 mm; DN3 - 300 mm.

Digital displays are offered in four colours: red, green, yellow and

blue.

Basic installations are applied for measurements and indications of:

temperature, humidity, time, pressure, flow, rotations, pulses, and also

the gas content and material quantity. These DN displays together with

an external measuring element or transducer can display any physical

quantity and co-operate with external devices equipped with an RS-

Each customer obtains a service manual together with the display

unit. The standard version includes the digital diode display field and

the unit field. The number of characters and the display colour are

expressed by the ordering code or defined by the customer.

The display field brightness is established automatically in accordance

with external conditions. The unit can be selected from the list inserted

CHOICE OF THE DISPLAY CHARACTER SIZE

In order to ensure the optimal read-out for each application one must

choose the appropriate height of the display digit.
