They are meant to be operated by a computer or Plant PLC to display production line information or line fault messages. These displays are NOT commercial displays which are manually updated by a keypad. They are in rugged enclosures and we offer modules to convert them to all standard industry communications protocols. Typical viewing distance is about 50 feet per one inch of digit height. All of our alpha-numeric displays are capable of scrolling messages of 240 characters or less.
Larger message scrolling capabilities are available.
