Belimo provides a full range of devices for Direct Digital Control (DDC) for Building Automation Control (BAC) with integrated digital communications protocols Modbus and BACnet.
System integrators can take full advantage of Belimo field devices' flexible control with built-in BACnet or Modbus digital communication protocols. Actuators and sensors integrated directly to the Building Management System which allows the system integrator to utilize existing industry software to perform all required field device setups, monitoring, and control of connected devices. No additional hardware is required, thus eliminating errors and reducing commissioning time. Expensive home-run wiring associated with traditional DDC systems connected to analog field devices is avoided.
