INBACKNX1K20000 – BACnet/IP to KNX Gateway for 1200 Points

INBACKNX1K20000 – BACnet/IP to KNX Gateway for 1200 points. 

The INBACKNX1K20000 is a high-capacity protocol gateway developed by HMS under the Intesis brand, specifically designed to integrate BACnet/IP systems with KNX TP installations. Supporting up to 1200 points, it is ideal for large-scale building automation projects requiring real-time control and monitoring of KNX devices from BACnet-based BMS, SCADA, or DDC platforms.

This industrial-grade device operates as a BACnet/IP Server, exposing KNX datapoints as native BACnet objects and enabling full bidirectional communication. The gateway supports COV (Change of Value) functionality, allowing BACnet clients to subscribe to updates on KNX variables and receive changes in real time. All functionality and parameter mapping is handled seamlessly through the onboard software interface.

Thanks to its robust design and wide compatibility, the INBACKNX1K20000 is a powerful enabler of interoperability between different smart building systems, ensuring flexibility in hybrid infrastructures. Its configuration and firmware updates are managed via the RS232 console port and the intuitive web interface for IP setup and diagnostics.
