HD67818-KNX-B2 Industrial PROFINET slave to KNX TP converter for building automation

Industrial PROFINET slave to KNX TP converter, housing type B (wide), DIN rail mount. 

The HD67818-KNX-B2 is a reliable industrial-grade converter designed to connect PROFINET slave devices such as Siemens PLCs with KNX TP networks used in building automation systems. It allows smooth data exchange between industrial and residential infrastructures where lighting, HVAC, or energy metering are controlled via KNX. This makes it ideal for cross-domain integration in smart buildings and industrial complexes.

With robust triple galvanic isolation between KNX–Power Supply, KNX–Ethernet, and Power Supply–Ethernet, the converter is resistant to electromagnetic interference and suitable for demanding environments. Its wide temperature range from -40°C to +85°C enables use in outdoor cabinets, substations, and industrial enclosures. The DIN rail mount and compact housing type B ensure easy integration in control panels.

The converter supports 1440 bytes for reading and writing, making it capable of transferring large datasets. Using the free SW67818 software, users can configure each PROFINET and KNX communication frame in detail, defining the byte mapping and message structure. This flexibility ensures compatibility with customized BMS or SCADA applications that require precise I/O control and feedback.
