NATA 7351  Weather Displays 


Displays enable you to display climate data - Ambient Temperature (AT), Relative Humidity (RH), Air Pressure (AP), Real Time. One display consists of one or several information terminals, one control device and sensors block.

Information Modules:

"NATA 7351 C"

Real time displaying.

"NATA 7351 T"

Ambient temperature displaying.

"NATA 7351 P"

Air pressure displaying.

"NATA 7351 H"

Relative humidity displaying.

(630...800 mm)

Additional Information:

- up to 400 information displays can be controlled by one control device (RS 485 network)

- there's a capability of customer's logo plotting

- main difference from the model "NATA 7305" is using of LED numeric displays as indicators

Conjunctive dimensions of single NATA 7351's terminal (all modifications)

User adjustable parameters:

- brightness

- color ( for two-color displays)

- interval between time/humidity displaying (for models with combined fields)

- interval between temperature/pressure displaying (for models with combined fields)


This complex uses "master-slave" architecture. Control device with sensors block is located at any place and it is connected with outdoor "slave" displays.
