MEDIALED displays are the ideal instrument to spread messages in public places. the bright part of the device is a series of leds (light emission diode) of super bright typology of selected quality. this kind of led together with some precious technical shrewdness make the medialed display well readable even with strong sun-light and they guarantee a high reliability for a long time.
Large moving message led display for long distance viewing
The message can be visualized with slide effect or with 15 different apparition effects that make it more spectacular. The message programming is performed with an infrared rays remote control keyboard supplied with equipment (the smallest model ML30R is an exception because it has an integrated keyboard). You can easily fit in any message and small sketches. It is possible to perform the programming by a personal computer and a software (optional). The display keeps memory of the message when it is switched off but not for more than 90 days. It is possible to visualize time, date and temperature. Moreover it is possible to visualize a Days-Countdown with respect to a scheduled date, for example: the opening of a shop, the premier of a film or a New Year's eve. Regarding industrial automation it is possible to connect the display to a PC/PLC. The display can receive the message by serial port or it can receive only an imput to visualize one of 8/255 pre-memorized messages. The imput can be gived by a serial command or 8 dry contacts N/O or 8 bit binary code.
The range The Medialed range is composed of 17 standard models with dimensions that go from Cm. 29 x 7,5 to Mt. 10 x 1. On demand it is possible to carry out personalized dimensions. Models are available with only one colour (Monocolor) to choose among red (standard), green, yellow, amber and blue (optional) and Multicolour models that can visualize at the same time 16 colours mixed with red and green (yellow, lemon, orange etc). All of the models with more than a meter in length are especially planned to be installed outdoors exposed to the atmospheric agents (IP55). Besides it is possible to ask for a greater level of protection for cases in which the display has to be installed in a more critical environment, for example in places where strong throws of water are used from the bottom upward (IP65) or in an industrial shed where there are very aggressive acid vapours. You can ask for the detailed list of all the available models with the characteristics and prices, selecting On-line application form.

Medialed is a device for information.
It's very effective when there is the necessity to gain the attention and to provide in real time pieces of information readable even from long distances (up to 80 meters). The superbright models are used with excellent results even in outdoor environment under the direct sunlight.
Some examples of displayable characters in different environments:
- Factories: for service messages, info about the orders, production data, safety recommendation, occurred injuries data, workings description, materials dislocation, alarms, machines errors, etc;
- Hospitals: for first aid regulations and for provided services;
- Parkings: for parking availabilities and service info;
- Expositive stands: to advertise products and offered services;
- Waiting rooms and entrances for the public: for general pieces of information.
Medialed can be interfaced to a PC or PLC or a network with the following connection types
- RS232
- RS422
- RS485
- Ethernet
- Wi-Fi
- Radiomodem
- GSM via SMS sending
- GPRS via Internet
- 8 bit parallel input with binary encoding for the selection of pages previously stored
- Dry contacts N/O for the selection of pages previously stored
The Medialed displays standard production is made up by 20 models which are different from each other for the character height and for the number of characters displayable simultaneously.
Characters number
According to the number of characters displayable simultaneously the models are divided in three categories, they can respectively visualize 10, 13 and 20 characters.
Upon request we can produce custom display with a different number of characters (up to 60).
Characters height
The following heights are available:
- Cm. 3, readable from about 9 meters;
- Cm. 5, " 15 meters;
- Cm. 7, " 21 meters;
- Cm. 8, " 24 meters;
- Cm. 11, " 33 meters;
- Cm. 16, " 48 meters;
- Cm. 20, " 60 meters.
To choose the suitable to your needs you have to ask yourself the following questions:
- Which is the maximum distance from which the message has to be readable?
- I need to see a word or set of words that stand still on the screen (for example, the code of a product)? If yes, how many characters it takes up?
- How do I want to control the display? ( see how do I interface );
- The color red is fine or I want a different color? (green, yellow, blue);
- It must be installed in a indoor environment or outside exposed to the weather?
- Particular aggressive acidic vapors or dust are present in the environment?
- What power-supply I have available at the installation site? (12V, 24V, 110V, 220V).
If you send us a request with the above information we can provide you a quotation quickly.
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.
