HD67G67-G43-VPN-B2 MQTT and HTTP/REST Server converter with LTE and VPN

HD67G67-G43-VPN-B2 connects MQTT and HTTP/REST Server communication through Ethernet, LTE, and VPN.

HD67G67-G43-VPN-B2 is an industrial MQTT / HTTP/REST Server converter with VPN, designed to integrate communication based on MQTT with systems using HTTP/REST Server. This model is well suited for telemetry applications, Internet of Things projects, remote monitoring systems, and modern automation installations where reliable data exchange is required between devices, network services, and higher-level platforms.

The HD67G67-G43-VPN-B2 variant offers Ethernet and SIM LTE connectivity, and it also supports VPN service, which allows secure access to data and communication with the device even in distributed installations. This makes it a practical solution for system integrators and maintenance teams who need a stable connection to remote sites, field stations, control cabinets, or devices operating outside the local plant network.

HD67G67-G43-VPN-B2 supports both MQTT and HTTP/REST Server at the same time, which means it can act as a practical link between devices, applications, and services using different data exchange methods. This approach simplifies integration, reduces the number of additional components in the system, and helps organize the communication architecture of the project more efficiently.

The manufacturer provides the possibility to define HTTP/REST parameters, MQTT line parameters, the list of HTTP/REST clients, and communication endpoints. As a result, the converter can be accurately adapted to the needs of a specific application, whether the task involves publishing measurement data, sending operating statuses, handling alarms, or integrating with a higher-level IT system.

The compact housing type B, 35 mm DIN rail mounting, wide power supply range of 8..24V AC and 12..35V DC, and operating temperature from -40°C to +85°C make HD67G67-G43-VPN-B2 suitable for demanding industrial environments. The G43 version also uses an LTE module with Micro-SIM support and an SMA female antenna connector, which helps create a reliable mobile communication link in the field.
