  • The BACplus-IP is a digital controller fully programmable with a variety
    of combinations of input/output configurations using modular boards.
  • It supports communication protocols such as BACnet IP, BACnet MS/TP and Modbus/RTU.
  • It is BACnet BTL certified in appliance with B-AAC (BACnet Advanced Application Controller) standards.


  • High resolution colour touch screen allows you to see and lock all the control points of its subnetwork in real-time.
    The user can choose to use the keyboard found on the touch screen
    or a web browser for the initial configuration of the controller
    (networking and general information).
  • Allows you to have a modular layout of the inputs/outputs and is compatible with Strato Automation EXP series expansion boards.
  • Quick assembly of the modular boards using a snap track system.
    Thanks to its modularity, this controller offers tailored solutions according to the actual needs of the project.
  • Greatly increases the capacity of the logical outline network and enables integration with third party products.
  • Greater flexibility in programming.
  • Removable terminals that are at a 45° angle to facilitate the connections.
  • Mini USB connection for easy access to the BACnet MS/TP network.
