Multisystem room automation is of great importance both for efficient operation of buildings and for the individual comfort of users and, over and above that, to offer substantial savings potential. In the Beckhoff I/O system, an extensive range of over 400 bus terminals is available to building technicians for the connection of all building sensors and actuator systems.
The new BC9191 room controller closes the gap in price-sensitive projects with firmly defined functions. By bundling certain functions in one module, the compact controllers are ideally suited, for example, for installation in hotel rooms or office spaces. Rooms or areas with repetitive requirements only require one-time programming of the room controller, which is then simply duplicated, depending on the number.
The BC9191 can be used as a compact controller or as decentralised intelligence for room control. Pre-installed software functions facilitate commissioning, and, on top of that, the BC9191 can also be freely programmed using the TwinCAT automation software. For networking, the room controller is equipped with two Ethernet ports with integrated 2-channel switch. The I/O stations can thus be configured with a line topology, instead of the classic star topology.
In order to implement additional functions, the BC9191 can be modularly extended with the entire range of bus terminals via the K-bus interface. Standard terminals and the sub-bus systems relevant for building automation, such as EnOcean, LON, EIB, DALI and M-bus, are optionally expandable.
