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

Industrial BACnet IP Master to MQTT Broker Converter with LTE

HD67C08-IP-G43-B2 is an industrial converter that combines the BACnet IP Master function with a fully integrated MQTT Broker, designed for use in modern automation systems, BMS infrastructures, and IoT applications. The G43 version includes an LTE module with a SIM card slot, ensuring stable communication even in locations without reliable Ethernet connectivity. This makes it an ideal solution for remote monitoring, HVAC integration, building management, and cloud data exchange with high operational reliability.

The device offers a wide range of industrial features — from galvanic isolation between Ethernet and power supply to full support for BACnet IP and MQTT protocols, as well as 10/100 Base-T Autosensing communication. All wired connections are made via a standard RJ45 port and a 2-pin 5 mm terminal block for power input, enabling easy installation inside control cabinets.

The converter is mounted on a DIN 35 mm rail, features compact dimensions of 70 × 60 × 95 mm, and can operate in an extended industrial temperature range from -40°C to +85°C (according to the technical documentation). This makes it suitable for demanding industrial applications where reliability under harsh conditions is essential.

Key Features

• Conversion between BACnet IP Master and MQTT Broker.
• Ethernet + LTE (SIM) connectivity in the G43 version.
• Automatic 10/100 Mbps communication speed detection.
• Ability to define MQTT client lists and map BACnet objects to MQTT topics.
• Galvanic isolation between Ethernet and power.
• Configuration supported via SW67C08 software (clickable link below).
• Durable industrial B2 Modulbox housing for DIN-rail installation.
