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

Industrial BACnet IP to MQTT converter with LTE and eSIM

The HD67C08-IP-G43-E-B2 is an advanced industrial converter that integrates a BACnet IP Master interface with a built-in MQTT Broker, making it ideal for building automation, HVAC systems, and modern IoT applications. The G43-E variant provides full LTE connectivity with support for both a physical SIM card and an integrated eSIM, ensuring maximum communication reliability even in locations with limited wired network access.

The device supports 10/100 Base-T Autosensing communication for both BACnet and MQTT, offers galvanic isolation between the Ethernet and power sections, and operates within a wide power range of 8…24V AC / 12…35V DC. The compact B2 Modulbox enclosure allows quick installation on a DIN 35 mm rail, making the converter a practical solution for industrial environments.

According to the technical specification, the unit operates within an extreme temperature range from -40°C to +85°C, and its dimensions 70 × 60 × 95 mm make it suitable even for very compact control cabinets.
