HD67C09-IP-G43-E-VPN-B2 – BACnet IP Slave to MQTT Broker converter with LTE, eSIM and VPN

Industrial BACnet IP Slave to MQTT Broker converter with LTE, eSIM and VPN service.

The HD67C09-IP-G43-E-VPN-B2 is an advanced industrial converter designed for secure and reliable integration of devices and systems operating as BACnet IP Slave with modern MQTT-based IoT platforms. The device combines BACnet IP Slave functionality with a built-in MQTT Broker and an integrated VPN service, enabling encrypted remote data transmission.

The G43-E-VPN version is equipped with an LTE module supporting both a physical SIM card and an integrated eSIM. This ensures maximum communication availability and redundancy, even in locations without fixed Ethernet infrastructure. The built-in VPN service creates a secure communication tunnel between BACnet IP devices and BMS, SCADA or cloud-based systems.

Network communication is handled via the RJ45 Ethernet port and LTE connectivity, with support for 10/100 Base-T Autosensing data rates for both BACnet IP and MQTT. The converter operates as an MQTT Broker, enabling publishing and subscription of BACnet data within IoT environments.

Galvanic isolation between the Ethernet interface and the power supply improves system reliability and protects the device against electrical disturbances commonly present in industrial environments. The compact B2 Modulbox enclosure allows fast installation on a DIN 35 mm rail.

With compact dimensions of 70 × 60 × 95 mm and a wide operating temperature range from -40°C to +85°C, the HD67C09-IP-G43-E-VPN-B2 is well suited for harsh industrial conditions and space-limited control cabinets.
