HD67952-B2 Industrial PROFINET Slave to MQTT Converter with TLS Encryption and DIN Mount

Industrial PROFINET Slave to MQTT converter, housing type B (wide), DIN rail mount. 

HD67952-B2 is an advanced industrial communication gateway that enables data exchange between a PROFINET Master (such as a SIEMENS PLC or SCADA system) and an MQTT server. It is designed to simplify the integration of industrial systems with cloud-based platforms and IoT architectures, providing seamless connectivity with brokers such as AWS IoT, Microsoft Azure, Mosquitto, and many others. The converter supports both data publishing and subscription from/to MQTT topics, enabling real-time telemetry and remote control. This device is ideal for applications in smart manufacturing, predictive maintenance, and remote monitoring of automation assets. Through its PROFINET interface, it collects data from industrial controllers and securely pushes it to the MQTT server using standard protocols. The encryption over TLS/SSL ensures secure communication in environments where data confidentiality and integrity are critical. The configuration process is user-friendly and intuitive, carried out using the free SW67952 software. Integrators can easily define MQTT topics, map data between protocols, and adjust network parameters. This reduces deployment time and allows fast integration with existing automation infrastructure.

Housed in a robust type B industrial enclosure, the HD67952-B2 is intended for DIN rail mounting inside control cabinets. Its compact form factor (60 x 35 x 95 mm) makes it suitable even for space-constrained environments. The device features a single Ethernet port (RJ45) used for both PROFINET and MQTT communication. Thanks to auto-sensing 10/100 Base-T support, it easily adapts to the connected network without additional setup. Power input is flexible, accepting 8...24VAC or 12...35VDC, connected through a 2-way 5mm screw terminal. The operating temperature range is extremely wide (-40°C to +85°C), making it reliable in harsh industrial environments, including outdoor cabinets or high-vibration zones. The approximate weight of 200g ensures easy installation on standard DIN rails.

This PROFINET to MQTT converter allows industries to step into the world of IIoT without overhauling existing infrastructure. By bridging deterministic fieldbus protocols with modern, lightweight publish-subscribe models, it enables cloud analytics, dashboards, and event-driven control systems to work directly with shop-floor equipment. The HD67952-B2 is a key component for organizations embracing digital transformation. The gateway is compatible with MQTT brokers that support QoS, retained messages, authentication, and secure connections. It is an excellent tool for system integrators, OEMs, and machine builders looking to connect PLC-based systems with MQTT-based IoT platforms while preserving cybersecurity and protocol compatibility.
