HD67C21-G43-E-VPN-B2 – industrial PROFIBUS Master to MQTT Broker converter with VPN, LTE and eSIM

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

HD67C21-G43-E-VPN-B2 is an industrial communication converter designed to integrate PROFIBUS networks operating as Master with systems based on MQTT Broker. The device enables secure and reliable transmission of process data from PROFIBUS installations to supervisory systems, cloud platforms and Industrial IoT applications.

A key advantage of the HD67C21-G43-E-VPN-B2 is the integrated VPN service, which provides encrypted remote access to PROFIBUS data and infrastructure. Combined with LTE connectivity using SIM and embedded eSIM, the converter is ideal for distributed industrial installations, mobile assets and locations without permanent wired network access.

The device operates as an MQTT Broker, allowing both publication and subscription of data directly from the PROFIBUS Master network. Communication can be handled via Ethernet LAN or mobile LTE networks, enabling flexible system architectures and seamless integration with SCADA systems, MES platforms and modern IoT solutions.
