HD67931-B2-160 Industrial M-Bus to MQTT Converter for 160 devices

HD67931-B2-160 – Industrial M-Bus to MQTT converter, master M-Bus up to 160 slaves, housing type B (wide), DIN rail mount.

The HD67931-B2-160 is a powerful industrial-grade gateway designed to seamlessly connect M-Bus networks with MQTT-based IoT platforms. Supporting up to 160 M-Bus slave devices, it provides a scalable solution for large infrastructures such as smart buildings, energy monitoring systems, water distribution networks, and industrial metering. Its wide compatibility with meters from vendors like SIEMENS, Kamstrup, Maddalena, Sontex makes it a universal choice for integrators working across multiple sectors.

This converter ensures fast and secure data transfer to IoT servers through the MQTT protocol, with support for TLS/SSL encryption. Security is a key aspect in critical infrastructures, and this device guarantees data integrity and confidentiality. The integration into Building Management Systems (BMS) or cloud IoT platforms becomes straightforward thanks to the intuitive configuration process provided by the SW67931 software. Users can define MQTT and M-Bus parameters, manage variables, and update firmware directly from their PC.

The HD67931-B2-160 is designed for industrial environments, featuring a wide power supply range of 18...35V DC or 15...21V AC, operating temperature from -40°C to +70°C, and robust galvanic isolation between Ethernet and M-Bus. Its compact design (71x60x95 mm) and DIN rail mounting allow easy installation in control panels and distribution cabinets. With low power consumption and a maximum startup demand of 30W, it ensures efficient operation even in demanding installations requiring high reliability and 24/7 uptime.

HD67931-B2 allows to publish the data read from MBus meters into a MQTT Server. These gateways allow a fast and easy access to the IoT world and they are compatible with IoT Servers that support MQTT protocol. The MQTT communication can be encrypted using TLS / SSL protocols, ensuring a secure communication. They allow to monitor MBus meters (like SIEMENS, Kamstrup, Maddalena, Sontex, etc.). Converter is easy to configure thanks to free SW67931 software.
