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

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

HD67C21-G43-E-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 installations to supervisory, analytical and cloud-based platforms.

With support for Ethernet LAN and LTE connectivity using SIM and embedded eSIM, the HD67C21-G43-E-B2 is well suited for distributed industrial installations and locations where wired network access is limited or unavailable. PROFIBUS data can be published to MQTT topics and accessed by multiple clients in real time.

The device operates as an MQTT Broker, allowing both publication and subscription of data directly from the PROFIBUS Master network. Communication can be handled via Ethernet or mobile LTE networks, providing flexibility in system architecture and seamless integration with SCADA systems, MES platforms and IoT applications.
