HD67G67-B2 MQTT and HTTP/REST Server converter for Ethernet communication

HD67G67-B2 integrates MQTT and HTTP/REST Server communication in Ethernet networks.

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

The HD67G67-B2 variant has been designed for Ethernet communication, which makes it easy to deploy in industrial installations, building systems, and integration projects where simple, structured, and predictable communication is essential. It is a practical solution for system integrators, machine builders, and maintenance teams who want to connect field devices with supervisory software without using a complex intermediate infrastructure.

HD67G67-B2 supports both MQTT and HTTP/REST Server at the same time, so it can serve as a convenient integration point between different methods of data exchange. This approach simplifies the communication architecture, reduces the number of additional devices, and makes deployment easier in projects where data from one system layer must be organized and made available to higher-level applications.

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 its task is to publish measurement data, transfer operating statuses, handle alarms, or integrate with higher-level industrial software.

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-B2 suitable for demanding industrial environments. An additional advantage is the electrical isolation between Ethernet and power supply, which supports reliable operation in installations where communication stability is critical.
