Industrial J1939 to MQTT Broker converter with LTE, eSIM and VPN for IoT HD67C17-G43-E-VPN-B2

Industrial J1939 to MQTT Broker converter with LTE, eSIM and VPN HD67C17-G43-E-VPN-B2

HD67C17-G43-E-VPN-B2 is an industrial communication converter designed for secure integration of J1939-based networks with modern IoT platforms, SCADA systems and cloud applications using the MQTT Broker communication architecture. The device enables reliable and encrypted data exchange between J1939 CAN buses and Ethernet or cellular LTE infrastructures.

The G43-E-VPN variant combines LAN and LTE connectivity with support for both a physical SIM card and an embedded eSIM, as well as an integrated VPN service. This ensures a high level of cybersecurity, operator flexibility and stable communication for mobile machinery, special-purpose vehicles and distributed industrial installations.

J1939 communication is handled via a dedicated CAN interface with data rates up to 1 Mbps, while MQTT data exchange is performed through RJ45 Ethernet with 10/100 Base-T Autosensing and via the LTE cellular network. Galvanic isolation between Ethernet and the power supply improves resistance to electromagnetic interference and increases operational safety in harsh industrial environments.

The converter is housed in a compact B2 Modulbox enclosure designed for DIN 35 mm rail mounting. It supports reliable operation in extreme environmental conditions with an operating temperature range from -40°C to +85°C. Compact dimensions of 70 × 60 × 95 mm allow installation inside space-constrained control cabinets.
