HD67951-B2 Industrial PROFIBUS DP Slave to MQTT Converter with TLS/SSL Encryption

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

The HD67951-B2 is a high-performance industrial protocol converter designed to enable seamless data exchange between a PROFIBUS DP Master (such as Siemens PLCs, supervisory control systems, or industrial automation controllers) and a MQTT server in IoT infrastructures. It is particularly suited for applications where secure data transmission is critical, as it supports TLS/SSL encryption to protect sensitive operational information. This makes it a reliable choice for both factory automation and remote monitoring systems.

By integrating PROFIBUS networks with MQTT, the HD67951-B2 acts as a gateway to the Industrial Internet of Things (IIoT), allowing real-time publishing and retrieval of process data. The converter is compatible with most IoT cloud platforms and MQTT brokers that comply with the standard protocol. Its robust design with a wide operating temperature range (-40°C to +85°C) ensures dependable operation in harsh industrial environments, from cold storage facilities to high-temperature manufacturing plants.

Installation is straightforward thanks to the DIN rail mount housing type B, which offers a compact yet durable enclosure for panel integration. The device configuration is simplified by the free SW67951 software, allowing engineers to set parameters quickly without advanced coding. This ease of setup reduces commissioning time and minimizes downtime during system integration or upgrades.
