HD67937-IP-B2 BACnet IP Master to MQTT Converter for Secure Industrial IoT Integration

Industrial BACnet IP Master to MQTT converter, housing type B (wide), DIN rail mount.

HD67937-IP-B2 allows to publish the data received from BACnet Slaves into a MQTT Server. These gateways allow a fast and easy access to the IoT world and they are compatible with IoT Servers that support MQTT. The MQTT communication can be encrypted using TLS / SSL protocols, ensuring a SECURE and SAFE communication.

The HD67937-IP-B2 converter has been designed specifically for industrial automation and building management systems, where a seamless integration between BACnet/IP networks and MQTT-based IoT platforms is required. By acting as a BACnet IP Master, the device can collect data from multiple BACnet slave devices such as HVAC controllers, lighting systems, sensors, or energy meters, and publish this data directly into a central MQTT broker. This allows facility managers, SCADA systems, and IoT dashboards to monitor and control BACnet devices in real time, even across distributed sites.

Thanks to its DIN rail housing type B (wide), the converter is easy to install inside electrical cabinets and control panels. The robust design ensures stability even in harsh environments with operating temperatures ranging from -40°C to +85°C. With a wide power supply range of 8…24VAC or 12…35VDC, the device can be powered from different industrial sources, making it highly flexible in various application scenarios. The RJ45 connectors for both BACnet IP and MQTT communication guarantee reliable network connectivity at 10/100 Base-T with autosensing.

One of the key benefits of the HD67937-IP-B2 is its support for encrypted MQTT communication. Using TLS/SSL protocols, all exchanged data can be protected against cyber threats, ensuring that sensitive information such as energy usage, HVAC parameters, or building automation control signals are transmitted securely. This makes the converter fully compliant with modern cybersecurity requirements for Industry 4.0 and smart building applications.

The converter is configured using the free SW67937 software, which offers a user-friendly interface for setting up both BACnet and MQTT communication parameters. This tool allows engineers to quickly map BACnet objects to MQTT topics, adjust communication rates, and define secure connection parameters for the MQTT broker. By simplifying the configuration process, commissioning time is reduced, and system integrators can deploy the gateway without the need for advanced programming skills.

Typical use cases include HVAC monitoring, energy management systems, and integration of legacy BACnet-based equipment into modern IoT platforms. For example, an organization can use this converter to publish real-time BACnet sensor data to a cloud platform for predictive maintenance, or to integrate building systems with smart city infrastructure. The compact size (60 x 36 x 95 mm) and low weight (approx. 200 g) make it suitable for installations with limited space.
