The Fusion range of Large digit slave displays let you clearly see important information from a distance. We make large displays which accept most common ASCII data signals such as RS232, RS422 and RS485. These are ideal for crane load displays, weighbridge displays, temperature, humidity, power, RPM etc.

The largest versions such as this 16 inch large display are ideal for use in large factories and outdoor installation

Very large displays

The Fusion family accepts the following signals:-

  • RS232 ASCII
  • RS485 ASCII
  • RS422 ASCII

All common baud rates are accepted and the displays can extract data to display from complex strings.

Uniquely, these displays can also be easily scaled to read your process variable in different units, for example the data might be in kg but you want to display pounds. Thanks to a user-friendly calibration system, this sort of flexibility is easy to achieve. Displays are available to show your measurement in 3,4,5 or 6 digit format. We can also print units text on the display to show kg, oC, Bar, %rh, mmHg, litres, gallons, tonnes etc.
