The BD-3 Body Module serves as the base for your entire modular configuration. It is designed to house both the main Brain Module — the intelligent control unit — and up to three different sub-modules.

Each sub-module is intended for a specific task: for example, the Locker Module allows control of 4 or 8 lockers, the Door Module manages access to doors, including locks and readers, and the third sub-module can be used for security features or, for instance, lighting control.

Up to 31 BD-3 Body Modules can be connected in a single line and centrally managed by the first unit equipped with the Brain Module. This allows the system to scale easily while maintaining centralized, intelligent control. 

Together, these components form a unified controller network, with each BD-3 serving as a building block in a robust, scalable, and seamlessly integrated system.
