HD67C06-G43-E-B2 Industrial Modbus TCP Master and MQTT Broker Converter with LTE SIM and eSIM

HD67C06-G43-E-B2 – Industrial Modbus TCP Master and MQTT Broker with LTE SIM and eSIM.

The HD67C06-G43-E-B2 is a high-performance industrial converter designed to integrate Modbus TCP Master systems with modern MQTT Broker infrastructures. It combines Ethernet communication with both a physical LTE SIM slot and an embedded eSIM module, ensuring continuous and redundant connectivity for remote, distributed or mission-critical automation environments.

Engineered for demanding industrial conditions, the device features a wide operating temperature range from −40°C to +85°C, galvanic isolation between power supply and Ethernet, and robust EMC protection. It is housed in a compact DIN-Rail Modulbox type B, making it easy to install in control cabinets, automation panels and IoT edge enclosures.

Key Features of the HD67C06-G43-E-B2

• Modbus TCP Master for polling and controlling Modbus TCP field devices.
• Built-in MQTT Broker supporting publish/subscribe communication for industrial IoT.
• Three communication interfaces: Ethernet LAN, LTE SIM and integrated eSIM.
• MQTT 3.1, 3.1.1 and 5.0 support with customizable topic structures and JSON templates.
• Galvanic isolation ensuring safe and reliable operation in harsh industrial networks.
• Extended temperature range from −40°C to +85°C.
• Robust EMC immunity suitable for industrial and high-interference environments.
• Status LEDs for device power, faults, Modbus TCP and MQTT communication.
• Compact DIN-Rail housing optimized for automation cabinets.
• Configuration via SW67C06 software with intuitive setup and flexible data mapping.

How the HD67C06-G43-E-B2 Works

Operating as a Modbus TCP Master, the converter connects to PLCs, energy meters, controllers, I/O modules and industrial sensors. All process data can be organized, processed and published as MQTT topics through the integrated MQTT Broker. Communication is fully bidirectional, enabling write commands from MQTT subscribers back to Modbus TCP devices.

The combination of LTE SIM and eSIM provides superior communication redundancy. If Ethernet is unavailable or unstable, the device can automatically rely on mobile data, ensuring continuous operation for remote facilities, outdoor installations and mobile industrial applications.
