          AC500 as IoT gateway






          Cost efficient and expandable solution
          • Scalable & platform-independent cloud connectivity
          • Adaptable functionality through interchangeable modules
          • Smart data handling on edge-level for cost-efficient cloud-solutions







          Connection of single controller


                                               Security level: optimized for remote units
                                               AC500 works as edge-gateway and is directly
                                               connected to the cloud. Security is established
                                               through TLS encryption.
