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

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

HD67G67-G43-E-B2 is an industrial MQTT / HTTP/REST Server converter designed to integrate communication based on MQTT with systems using HTTP/REST Server. This model is well suited for 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-G43-E-B2 variant offers Ethernet, SIM LTE, and eSIM connectivity, allowing the device to operate both in a local network and in distributed installations that require mobile communication. This makes it a practical solution for system integrators, machine builders, and maintenance teams that need to connect field devices with software systems without creating a complicated communication architecture.

HD67G67-G43-E-B2 supports MQTT and HTTP/REST Server at the same time, so it can work as a convenient integration point between different data exchange methods. This approach simplifies the communication structure, reduces the number of additional devices, and helps organize the overall project architecture in a cleaner and more efficient way.

The manufacturer allows configuration of 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 values, 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-G43-E-B2 suitable for demanding industrial environments. The G43 version uses an LTE module with support for Micro-SIM and eSIM, as well as an SMA Female antenna connector, which helps create a reliable mobile connection.
