    Systematic evolution

    Smart Display Link 4 (SDL4) is continues the advances made with SDL3. SDL4 is compatible with standard HDBaseT 2.0 and makes it possible to connect multiple panels to a single industrial PC.

    The familiar benefits of SDL3 have been enhanced with the latest data transfer speeds to meet the needs of Industry 4.0.


    The other specifications correspond with SDL3: CAT 6/7 cables are used, and the maximum distance between PC and panel is 100 meters. Of course, in addition to screen content, SDL4 also transmits data for touch screen operation, keys, LEDs and USB devices.

    The new standard for operator panel communication

    With HDBaseT 2.0, SDL4 transmits all the signals needed to operate the Automation Panel uncompressed over large distances. The modular design of B&R's industrial PCs and operator panels make it easy to upgrade existing installations with SDL4.

    SDL4 technology

    • SDL4 transmits all communication channels between PC and panel via a standard Ethernet cable.
    • Up to 100 m
    • Independent of operating system and software
    • Simplified cabling
    • Small connector – also suitable for tight feed-throughs
    • No need for a CPU in the panel
    • No load on the PC system
    • Optimal graphics performance
    • Long-term availability

    Multi-panel operation

    A primary difference between SDL3 and SDL4 is the ability to operate up to three Automation Panels on an Automation PC via an SDL/SDL4 splitter. If the PC system has an additional display interface (e.g. Automation PC 910 + Panel PC 3100), then it is also possible to operate an additional panel either with the same or different content.

    Flexible use with all product series

    The modular design of the Automation Panels allows flexible use of SDL and SDL4 for all product generations. SDL4 can therefore be implemented on existing swing arm systems and customized variants.
