In addition to direct data interfaces to external systems, most projects still require IO modules for control functions and for accepting external signals. These can be seamlessly integrated into the system architecture. Different module configurations are available depending on the requirements. All modules are controlled via an RS-485 interface using a self-monitoring data protocol, allowing these modules to be operated independently by the hub.


  • Centralized and decentralized integration of contact inputs, e.g. door/gate contacts.
  • Control of external components, such as video systems or other alarm systems.
