This type of display is used especially in industrial field when it's necessary to visualize clearly numerical data from long distances (from 5 up to 300 meters according to the models), for example in an industrial shed or in a sporting stadium, even if in presence of direct sunlight.

The bright part of the device is composed by a series of LED (Light Emission Diode). The Numeric Display can be integrated in a process of production connecting them to an industrial machine, a PC or a PLC by the following types of input: Profinet interface, Profibus, serial RS232/422/485; dry contacts N/O; parallel BCD or multiplex BCD; in tension (0-10V, 0-5V, 1-5V); in current (4-20 MA, 0-20 MA).

The "sequential counter" version can be operated by N/O dry contacts manually aloof by a remote control, infrared remote control or wired keyboard. The "sequential counter" version standard functions are: Up or Down (increase or decrease of a unit at each contact), Reset and Preset. Upon request is possible to implement particular functions such as: an increase of 10 units for each contact or when counter reaches a preset figure, through an relè contact output, it turns on an external device or an alarm siren. It's also available the "Timer" version: see Crono-Display series.

The available digit colors are: red (standard), green, yellow, amber and blue (optional). Displays can be built with digits number at will: from 1 up to 32.

The numerical displays are available with the following digit heights:

  • cm. 2 readable up to 6 meters;
  • cm. 5,6 " " " 15 meters;
  • cm. 10 " " " 30-40 meters;

You can ask for an available models detailed list with prices and features by selecting Info request. Models with digit heights cm. 2 e cm. 5,6 are built with "7 segments" type on resin blocks: they have a not excessive brightness and they are well readable closely and from any angle; this type of LED is recommended when the display must be installed in an indoor environment not illuminated directly by the sunlight. On every other model are assembled Superbright LED type: are well readable even at direct peak sunlight and then they are suitable for outdoor environment installation.

All models can be equipped with the preset chassis to be installed outdoors exposed to weather agents (IP55) or with a greater protection grade when it must be installed in in critical environment, such as in places where strong water jet are used also from bottom to top (IP65) or in an industrial building where there are very aggressive acid vapors.

Numerical-Giant is widely used in industry especially when there is a need to visualize numerical data that are clearly legible even at large distances (from 5 to 180 meters depending on models).
For example is used to show:

  • Number of produced pieces;
  • Speed of a conveyor belt;
  • Pallet's weight;
  • Processing time of a product;
  • The number of errors in the processing;
  • The target to be reached;
  • The number of the shelf from which withdraw the piece;
  • The number of the line that needs an intervention;
  • Shift loading / unloading of trucks in the parking area.

Numerical-Giant can be built with a number of digits up to 32.
Each digit is displayed by the classic 7 segments matrix.
With this type of matrix is possible to visualize all numbers, some letters and some other symbols:


Numerical-Giant can be interfaced to one ore more PC e PLC in network or directly to analog sensors and devices with the following types of connections:

  • Profinet interface
  • Profibus interface
  • RS232
  • RS422
  • RS485
  • Ethernet
  • Wi-Fi
  • BCD (Binary Coded Decimal)
  • BCH (Binary Coded Hexadecimal)
  • Parallel input 8-bit binary encoding
  • Analog voltage 0-10V input
  • Analog current 4-20mA input
  • Dry contacts N/O
  • Manual Radio control
  • Radiomodem
  • GPRS via Internet

The Numerical-Giant display standard production is made up by 28 models which differ from each other by the number and height of the digits. 

On all models you can implement various control cards and interface ( see How it connects ).

Numerical-Giant is available with the following digit heights:

  • cm. 2 readable up to 6 meters; 
  • cm. 5,6 readable up to 15 meters; 
  • cm. 15 readable up to 45-60 meters; 
  • cm. 23 readable up to 69-92 meters; 
  • cm. 32 readable up to 96-128 meters; 
  • cm. 47 readable up to 141-188 meters; 

Standard models have digits number from one (example: 9) to ten (9.999.999.999) but upon request we can implement up to 32 digits.

To choose the display that best suits your needs, you should ask yourself the following questions:

  • You should see only a numeric value or even letters or symbols?;
  • How many digits make up the largest value that must be displayed?;
  • From which distance the display should be readable?
  • How do you want to interface the display? ( see How it connects );
  • The color red is fine or you want a different color? (green, yellow, blue);
  • Do you want still writings on the side of the variable data? (ex.: produced pieces, goal etc.);
  • It must be installed indoors or outdoors?
  • Are present in the environment particular dust or corrosive acid fumes?
  • What type of Power Supply do you want? (12V, 24V, 110V, 220V).

Binary-coded decimal (BCD) encoding is a popular way in informatics and electronics to represent decimal number in Binary-code.

In this format every number's digit is represented by a binary code made up by four bits, where the value is between 0 (0000) and 9 (1001). The other six combinations can be used to represent symbols. For example number 127 is represented in BCD like this: 0001, 0010, 0111.

Because computers store data in bytes of eight bits, you can store a number for byte and fill the remaining four bits with zeros or one (as in the EBCDIC code), or put two digits per byte, packed BCD call mode. The packet BCD numbers normally end with a sign code, usually 1100 for + and 1101 for -. The number 127 is represented by 11110001, 11110010, 11110111 in EBCDIC and 00010010, 01111100 in packet BCD.

Although the BCD involves a considerable waste of bits (about 1/6 of unused memory in packed BCD), and in some cases it is preferable because it has a direct correspondence with the ASCII code. It is sufficient to replace the first four unused bits with 0011 to obtain the corresponding ASCII.

The BCD code is very popular in electronics, especially in digital circuits without microprocessor, because it facilitates the visualization of long digits of seven segment display, because each physical display corresponds exactly one digit. There are special integrated circuits that perform the conversion from BCD in the corresponding power-on sequence of segments. Even performing simple arithmetic is easier to be made of BCD digits for combinational logic circuits.

The BIOS of the personal computers store the date and time in BCD format, presumably for historical reasons.

The reading distance depends on the size of the characters that the display is capable of displaying. The reading distance does not depend on brightness. The following table shows the read range depending on size. By convention we refer only to character height.
