The UPWT-2 Universal Industrial Text Display – a flexible LED information system with IP65 and remote, wired communications enclosed in a rugged steel housing.

Display key process information in factories, offices and industrial locations improving control, efficiency and safety.

Like its smaller brother (the UPWT-1), UPWT-2 is a fixed-format (ie: one size) display for wall-mounting and offers industrial performance at an affordable price.

The UPWT-2 brings a much larger character height (120mm vs 60mm) offering distance readability over 40m in good conditions – ask us for details.

UPWT-2 can be reprogrammed remotely making it multipurpose and reusable – with a choice of communications protocols.

Sets of Characters

As well as English, the displayed text can contain characters from the following alphabets:
– PL, RU, DE, CZ, SK, HU, UA, LT, LV, NO, SE, FR, NL
– and special characters (for example % @ ° $ € < > + – = etc.)

The UPWT-2 can display 7 full digits as shown: 


Content, depending on the version of the device, can be transmitted by the following interfaces: – Ethernet (two-way communication) – RS485 (two-way communication) – RS422 – 232 (with optical isolation) – CL 20mA current loop (with optical isolation)


Displays communicate with the host system using one of the two protocols: – MODBUS RTU (RS485 interface only) – Uncomplicated R004 protocol developed by RGB Technology (included in the price of the device at purchase) Interfaces with two-way communication enable obtaining the acknowledgment of the receipt of the data by the display.
The specific capabilities of the device are as follows:

  1. Displaying the text in one verse or two verses (only for certain models of the devices). Two-verse devices have one interface, but they display the text in each verse independently.
  2. Displaying flowing or stationary messages (forced flowing text, forced stationary text, switching on the flow of the text automatically when the messages do not fit on the display).
  3. Available length of messages is from 1 to 100 characters.
  4. 20 different speeds of the text flow.
  5. Two font-faces of standard characters (normal and bold).
  6. Five font-faces of digits with a fixed width dedicated to display numbers, for example finished items, daily schedule, etc.. (two normal font-faces and three bold font-faces).
  7. Displaying current temperature (extra option).
  8. Two modes of brightness adjustment: manual (10 different brightness levels) or automatic (4 different profiles of the brightness sensor).
