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

HD67G67-G43-E-VPN-B2 connects MQTT and HTTP/REST Server with LAN, SIM LTE, eSIM, and VPN.

HD67G67-G43-E-VPN-B2 is an industrial MQTT / HTTP/REST Server - Converter designed for integrating MQTT communication with an architecture based on HTTP/REST Server. It is a practical solution for modern telemetry systems, IoT projects, remote monitoring, industrial automation, and data integration applications where information must be exchanged reliably between field systems, network services, and higher-level platforms.

The HD67G67-G43-E-VPN-B2 version stands out with its advanced LAN + SIM LTE + eSIM connectivity and active VPN Service. This combination gives system designers more flexibility because the converter can operate in a local Ethernet infrastructure as well as in remote installations that require mobile connectivity and secure access. It is especially useful in distributed applications where stable communication, remote reachability, and deployment flexibility are critical.

HD67G67-G43-E-VPN-B2 supports both MQTT and HTTP/REST Server over Ethernet and LTE, which makes it a strong integration point for process data, device statuses, alarms, and measurement values. This allows the converter to fit projects where MQTT-based data exchange must work together with software, applications, or services using HTTP/REST Server logic.

Another key advantage of this model is the possibility to define HTTP/REST parameters, MQTT parameters, the list of HTTP/REST clients, and the communication endpoints. This helps adapt the converter precisely to the project requirements and reduces integration time in systems that demand structured, predictable, and easy-to-manage data exchange.

The compact housing type B, DIN rail mounting, 8..24V AC and 12..35V DC power supply, and wide operating temperature range from -40 to +85°C make HD67G67-G43-E-VPN-B2 well suited for industrial cabinets, telemetry stations, remote infrastructure, and demanding field installations.
