HD67C23-G43-E-VPN-B2 PROFINET Slave to MQTT Broker Converter with VPN LTE eSIM

Industrial PROFINET Slave / MQTT Broker converter with integrated VPN service, LTE connectivity and eSIM, type B housing, DIN rail mounting.

HD67C23-G43-E-VPN-B2 is an advanced industrial communication converter designed to integrate PROFINET networks operating as Slave with infrastructures based on MQTT Broker. The device enables secure and reliable transmission of process data from automation systems to IoT platforms, SCADA systems and cloud environments.

The HD67C23-G43-E-VPN-B2 combines three essential elements of modern industrial communication: PROFINET Slave functionality, embedded MQTT Broker and integrated VPN service. Additionally, the device supports LTE connectivity via SIM card and built-in eSIM, allowing secure deployment in distributed systems without fixed wired infrastructure.

The integrated VPN provides encrypted remote access to PROFINET infrastructure, enabling secure monitoring, diagnostics and maintenance of field devices. This makes the HD67C23-G43-E-VPN-B2 ideal for energy systems, industrial automation, critical infrastructure and mobile applications.

On the automation side, the converter operates as a PROFINET Slave, while on the Ethernet/LTE side it functions as an embedded MQTT Broker. It allows publishing and subscribing MQTT topics, managing client access rights and seamless integration with SCADA, BMS, MES and Industrial IoT platforms.

Industrial design ensures:

• Electrical isolation between Ethernet and power supply
• Wide operating temperature range -40°C to +85°C
• Power supply range 8…24V AC / 12…35V DC
• DIN rail mounting (35 mm)
• Modulbox 4M industrial housing type B

These parameters guarantee stable operation in demanding industrial environments.
