HD67C23-G43-VPN-B2 PROFINET Slave to MQTT Broker Converter with VPN and LTE DIN Rail

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

HD67C23-G43-VPN-B2 is an industrial communication converter designed to integrate PROFINET devices operating as Slave with systems based on MQTT Broker. The device enables secure and reliable transmission of process data from PROFINET networks to supervisory systems, IoT platforms and analytical applications.

A key feature of the HD67C23-G43-VPN-B2 is the integrated VPN service, providing encrypted remote access to industrial infrastructure and process data. Combined with LTE connectivity via SIM card, the converter enables secure communication in distributed automation systems, remote installations and mobile industrial environments.

The device operates as a PROFINET Slave on the automation side and as an embedded MQTT Broker on the Ethernet/LTE side. It allows publishing and subscribing MQTT topics, managing client access rights and seamless integration with SCADA systems, BMS, MES and cloud-based platforms.

The converter provides:

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

These characteristics ensure stable operation in demanding industrial environments.
