HD67813-KNX-232-B2 Industrial Modbus RS232 Slave to KNX TP Converter DIN Housing B

Industrial Modbus RS232 slave to KNX TP converter, housing type B (wide), DIN rail mount.

HD67813 allows to communicate KNX TP with RS232 Modbus RTU devices like SCADA, HMI or Modbus controllers. This RS232 Slave version is ideal for projects where the converter must act as a Modbus slave device connected to a master system while still bridging data to the KNX TP bus. The robust housing type B ensures a solid mechanical design, suitable for DIN rail cabinets in both industrial and building automation environments. Converter is easy to use thanks to free SW67813 software, which simplifies configuration and makes integration straightforward.

Configuration:

Thanks to the SW67813 software on your PC you can:

• Define the parameters of Modbus line
• Define the parameters of KNX line
• Define the KNX messages that the Converter can accept
• Define the KNX frames that the Converter sends through the KNX line
• Define the map of KNX byte that must be written in the Modbus side
• Define the map of which Modbus registers must be written in KNX messages
• Update the device

The graphical interface of SW67813 makes mapping between KNX datapoints and Modbus registers simple and efficient. Users can quickly configure multiple datapoints, allowing flexible integration between smart building devices and legacy Modbus-based equipment.

Characteristics:

• Up to 1440 bytes in reading and 1440 bytes in writing
• Triple isolation between KNX - Power Supply, KNX – Serial, Power Supply - Serial
• Bi-directional information exchange between KNX bus and Modbus bus
• Mountable on 35mm Rail DIN

The 1440-byte memory capacity provides significant flexibility in managing large amounts of communication data, ensuring compatibility even with complex projects. Triple isolation enhances electrical protection, reducing risks of interference and safeguarding connected devices.
