HD67C21-G43-B2 – industrial PROFIBUS Master to MQTT Broker converter with LTE

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

HD67C21-G43-B2 is an industrial communication converter designed to integrate PROFIBUS networks operating as Master with systems based on MQTT Broker. The device enables reliable acquisition and distribution of process data from PROFIBUS field devices to supervisory, analytical and cloud-based platforms.

Equipped with Ethernet LAN and LTE connectivity via SIM card, the HD67C21-G43-B2 allows data transmission from PROFIBUS installations located in remote or mobile environments. PROFIBUS process values can be published to MQTT topics and accessed by distributed clients, making the device suitable for modern industrial IoT and monitoring architectures.

The converter operates as an MQTT Broker, enabling both publication and subscription of data directly from the PROFIBUS Master side. Communication can be handled through wired Ethernet or mobile LTE networks, providing flexibility in system design and simplifying integration with higher-level applications such as SCADA, MES and data analytics platforms.
