Industrial BACnet IP slave to Modbus TCP master converter, housing type A (slim), DIN rail mount.

HD67673 allows you to connect a BACnet Master (for example a Supervisory System, etc) with some Modbus TCP slaves. The converter provides seamless, bi-directional data exchange between BACnet IP devices and Modbus TCP equipment, ensuring compatibility between building automation and industrial control systems. With its slim housing type A, it is designed for installations where space is limited but performance and reliability are essential. Converter is easy to configure thanks to free SW67673 software, which helps engineers reduce commissioning time and simplify maintenance.

Configuration:

Thanks to the SW67673 software on your PC you can:

• Define the parameters of BACnet line
• Define the parameters of Modbus TCP line
• Define BACnet objects that contains the data read from the Modbus TCP slaves
• Define BACnet objects that contains the data to send to the Modbus TCP slaves
• Update the device

The configuration utility allows mapping of BACnet objects to Modbus registers in an intuitive way. This makes it possible to integrate complex systems such as HVAC controllers, energy meters, or lighting systems without rewriting control logic. Engineers can quickly create mappings for up to 1024 objects, making the device suitable for large-scale automation projects. The ability to update firmware directly ensures long-term support and compatibility with evolving standards.

Characteristics:

• Up to 1024 BACnet objects (Read+Write)
• Triple isolation between BACnet - Power Supply, BACnet - Modbus, Power Supply - Modbus
• Bi-directional information exchange between BACnet bus and Modbus bus
• Mountable on 35mm Rail DIN

These features ensure high flexibility and safety. The large number of supported BACnet objects allows integration of extensive building systems. The triple galvanic isolation improves robustness and protects the installation against electrical disturbances. Thanks to DIN rail mounting, the converter is easily integrated into new or existing control panels, while its slim design reduces space usage.
