HD67930-G43-B2 – Industrial Ethernet to MQTT Converter with LAN, LTE SIM and eSIM

HD67930-G43-B2 Converter – advanced Ethernet to MQTT gateway with LAN, LTE SIM and eSIM connectivity.

The HD67930-G43-B2 is an industrial Ethernet to MQTT converter designed for modern IoT and IIoT applications that require reliable data exchange between TCP/UDP-based devices and MQTT brokers or cloud platforms. Built in a robust Housing type B enclosure with DIN rail mounting and terminal block connectors, this model provides outstanding flexibility thanks to its dual connectivity options: traditional wired Ethernet and mobile communication using both a LTE SIM slot and a built-in eSIM.

This makes the HD67930-G43-B2 a versatile gateway for remote installations, distributed automation systems and environments where stable communication must be maintained even when wired networks are unavailable or unstable. The device supports two independent Ethernet-based protocols: TCP/UDP for general data transport and MQTT for structured IoT communication, enabling seamless transmission between industrial equipment and cloud or edge infrastructures.

Thanks to its compatibility with popular MQTT ecosystems such as Mosquitto, EMQX, HiveMQ, AWS IoT, Azure IoT Hub and Google Cloud IoT, this converter is ideal for telemetry, monitoring, data acquisition and distributed automation architectures.

Ethernet TCP/UDP and MQTT communication

The HD67930-G43-B2 supports bidirectional data handling using standard Ethernet (TCP/UDP) and MQTT. Data can be received from TCP/UDP sources and published to MQTT topics or vice versa, enabling:

• conversion of TCP/UDP data into MQTT messages,
• subscribing to MQTT topics to send commands to Ethernet devices,
• integration of IT and OT networks,
• implementation of cloud-based or hybrid architectures,
• edge computing scenarios and smart automation systems.

Both communication channels operate at 10/100 Base-T Autosensing, ensuring smooth adaptation to various industrial network environments.

LAN, LTE SIM and eSIM – full communication redundancy

One of the strongest advantages of the G43 variant is its triple connectivity:

• LAN (RJ45) for stable wired communication,
• LTE SIM slot for standard mobile connectivity,
• Integrated eSIM for deployments where no physical SIM is used.

This combination ensures redundancy, enabling the converter to:

• operate autonomously in remote or isolated locations,
• maintain communication during LAN downtime,
• switch between mobile operators when eSIM is used,
• simplify installation in systems where wired connections are difficult to implement.

Industrial design in Housing type B

The device is built in a compact Housing type B enclosure, sized 36 × 60 × 95 mm, suitable for DIN rail installation in industrial cabinets. Screw terminal connectors ensure reliable wiring, even under vibration or harsh environmental conditions.

The operating temperature range of -40°C to +85°C makes this converter suitable for demanding applications including outdoor installations, energy management systems, remote telemetry stations, utilities, transportation or heavy industry.
