HD67939-B2 Industrial CAN to MQTT Converter with TLS/SSL Security and IoT Integration

HD67939-B2 – Industrial CAN to MQTT Converter, housing type B (wide), DIN rail mount.

The HD67939-B2 is a powerful gateway designed to integrate CAN networks with modern IoT systems through the MQTT protocol. By enabling seamless bidirectional communication, this device makes it possible to publish data from CAN devices into an MQTT server as well as retrieve commands or variables from the MQTT environment back into the CAN network. Thanks to its compatibility with both CAN 2.0A and CAN 2.0B standards, it can be implemented across a wide range of industrial applications including automation, transport, energy distribution, and building management.

This converter supports secure communication using TLS/SSL encryption, ensuring that sensitive industrial data remains protected against interception and tampering. The ability to handle CAN data rates up to 1 Mbps combined with 10/100 Base-T autosensing Ethernet ensures reliable performance even in large-scale installations. The device is ideal for connecting legacy CAN-based equipment to modern IoT platforms, enabling real-time monitoring, predictive maintenance, and integration with cloud services or SCADA systems.

Configuration is straightforward thanks to the free SW67939 software. Users can easily define CAN and MQTT parameters, manage data mapping, and update the device firmware. The HD67939-B2 is designed for demanding industrial environments with an operating temperature range of -40°C to +85°C, a robust DIN rail housing, and a wide power supply input of 8…24 VAC or 12…35 VDC. With its compact size (60 × 36 × 95 mm) and low power consumption, it is an excellent choice for both retrofitting existing systems and implementing new IoT-ready installations.

HD67939-B2 allows to publish and get the data from/to a CAN network into/from 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. The MQTT communication can be encrypted using TLS / SSL protocols, ensuring a SECURE and SAFE communication.
