HD67950-B2 Industrial PROFIBUS DP Master to MQTT Converter with TLS/SSL Encryption

Industrial PROFIBUS Master to MQTT converter, PROFIBUS DP DPV0 support, housing type B (wide), DIN rail mount.

The HD67950-B2 is a high-performance industrial gateway that enables seamless communication between a PROFIBUS DP network in Master mode and an MQTT server. It is specifically designed for scenarios where data from multiple PROFIBUS Slave devices must be collected and transmitted to Industrial IoT platforms in real time. Thanks to support for TLS/SSL encryption, the converter ensures secure data transfer, making it suitable for applications where data confidentiality and integrity are critical.

This gateway allows quick and straightforward integration of PROFIBUS-based automation systems with modern IoT infrastructures. It can publish data to cloud services, SCADA systems, or any MQTT-compliant broker, enabling advanced analytics, remote monitoring, and predictive maintenance strategies. The device supports PROFIBUS speeds up to 6 Mbps and features an auto-sensing Ethernet interface, reducing installation complexity and ensuring optimal network compatibility without manual configuration.

With its housing type B designed for DIN rail mounting, the HD67950-B2 offers mechanical robustness and ease of installation in industrial control cabinets. The operating temperature range from -40°C to +85°C ensures reliable operation in harsh environments such as outdoor installations, production plants, and energy facilities. Configuration is simplified by the free SW67950 software, which provides an intuitive interface for setting up communication parameters quickly.
