HD67C20-G43-E-VPN-B2 – industrial NMEA2000 to MQTT Broker converter with VPN, LTE and eSIM

Industrial NMEA2000 to MQTT Broker converter with VPN, type B housing, DIN rail mounting, LAN connectivity with LTE SIM and eSIM.

HD67C20-G43-E-VPN-B2 is an advanced industrial communication converter designed to integrate NMEA2000 networks with systems based on MQTT Broker. The device enables reliable and secure transmission of measurement and diagnostic data to local or cloud-based IoT platforms, BMS and SCADA systems.

Thanks to the built-in VPN service and support for LTE connectivity using SIM and eSIM, the HD67C20-G43-E-VPN-B2 allows secure remote data access even in locations without fixed network infrastructure. NMEA2000 data can be published to MQTT topics and transmitted to distributed systems, making the device suitable for maritime, offshore, industrial and IoT applications.

The device operates as an MQTT Broker, allowing data publication and subscription directly from the NMEA2000 network. Communication can be handled via Ethernet LAN or mobile LTE networks, enabling flexible system architectures and reliable data exchange between field devices and higher-level applications.
