HD67C08-IP-G43-B2 – BACnet IP Master to MQTT Broker converter with LTE and Ethernet

The HD67C08-IP-G43-B2 is an industrial-grade converter that combines a BACnet IP Master interface with a fully integrated MQTT Broker, enabling seamless data exchange between building automation systems and cloud-based IoT platforms. The G43 variant includes an LTE module with SIM slot, ensuring reliable remote connectivity where Ethernet access may be limited or unavailable.

Designed for advanced BMS, HVAC, IoT and industrial automation applications, the converter offers automatic 10/100 Base-T Autosensing communication, electrical isolation between Ethernet and the power supply, and robust performance across a wide temperature range. All interfaces are easily accessible via an RJ45 Ethernet port and a 2-pin 5 mm terminal block for power, enabling quick installation in control cabinets.

The device is housed in a compact B2 Modulbox enclosure with DIN 35 mm rail mounting, measuring only 70 × 60 × 95 mm and weighing approx. 200 g. It supports reliable operation from -40°C to +85°C, making it ideal for demanding industrial environments.

Key Features

• Bidirectional conversion between BACnet IP Master and MQTT Broker.
• Ethernet + LTE connectivity (G43 version with SIM slot).
• Automatic 10/100 Mbps speed detection for both BACnet and MQTT.
• Mapping of BACnet objects to MQTT topics with configurable templates.
• List management for allowed MQTT clients and published/subscribed topics.
• Electrical isolation between Ethernet and power section.
• Compact DIN-rail enclosure optimized for industrial automation systems.

Configuration is performed using the dedicated software (Compositor SW67C08), which allows defining MQTT parameters, BACnet line settings, topic mapping and firmware updates.
