HD67935-B2 Industrial Modbus TCP Master to MQTT Converter with TLS/SSL Security

Industrial Modbus TCP master to MQTT converter, housing type B (wide), DIN rail mount.

The HD67935-B2 is a robust industrial gateway that enables seamless integration between a Modbus TCP Master network and the IoT ecosystem using the MQTT protocol. It allows reading data from multiple Modbus TCP slave devices and publishing it directly to an MQTT server, as well as receiving commands from MQTT and forwarding them to Modbus TCP devices. This makes it ideal for applications in building automation, process control, and industrial IoT systems.

The device is fully compatible with IoT servers and brokers that support MQTT, whether deployed on-premises or in the cloud. Thanks to TLS/SSL encryption, it ensures secure and reliable communication even in critical infrastructure environments. Its compatibility with 10/100 Base-T autosensing Ethernet simplifies installation, while the wide operating temperature range allows deployment in harsh industrial conditions, from manufacturing plants to outdoor cabinets.

The HD67935-B2 is easy to configure using the free SW67935 software, which provides a user-friendly interface for defining MQTT topics, Modbus communication parameters, and data mapping rules. Its wide power supply input range (18...35V DC and 8...24V AC) makes it suitable for diverse power environments, and the DIN rail mount design ensures fast integration into control panels and electrical enclosures.
