HD67672-IP-2-A1 BACnet IP slave to RS-232 Modbus slave converter for automatio

Industrial BACnet IP slave to RS-232 Modbus slave converter, housing type A (slim), DIN rail mount.

HD67672 allows you to connect a BACnet Master (for example a Supervisory System, etc) with a Modbus Master (for example a PLC, HMI, etc) in order to exchange the informations between the networks. Converter is easy to configure thanks to free SW67672 software. The device operates as a BACnet IP slave on the Ethernet side and as a RS-232 Modbus slave on the serial side, making it a highly versatile tool for integrating building automation and industrial control systems. Its compact DIN rail housing type A allows it to be installed in small spaces, making it suitable both for new projects and retrofit scenarios.

Configuration:

Thanks to the SW67672 software on your PC you can:

• Define the parameters of BACnet line
• Define the parameters of Modbus line
• Define BACnet objects that contains the data sent by the Master Modbus
• Define BACnet objects that contains the data to sent to the Master Modbus
• Update the device

The SW67672 configuration tool provides an intuitive environment for mapping RS-232 Modbus slave registers to BACnet IP slave objects. This makes Modbus field data available to BACnet supervisory systems, ensuring seamless integration without middleware. The software also supports firmware updates and diagnostic functions, which help integrators minimize commissioning time and maximize system reliability.

Characteristics:

• Up to 2048 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

The converter supports up to 2048 BACnet objects, which provides enough capacity for complex automation projects involving many data points. Its triple galvanic isolation protects the system from electrical noise and disturbances, ensuring stable communication between networks. Bi-directional data flow enables BACnet systems to read and control Modbus devices, and vice versa, making it suitable for BMS, SCADA, and energy management systems. The robust design makes the device ready for 24/7 continuous operation in demanding industrial environments.
