HD67844-B2 Industrial DALI to Modbus TCP Master Converter for 64 devices

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

The HD67844-B2 allows you to connect a DALI network (such as a lighting control system) with Modbus TCP slaves in order to exchange information between the two networks. This industrial gateway ensures bi-directional communication between the DALI and Modbus protocols, making it possible to integrate advanced lighting infrastructures with automation systems and building management platforms. Thanks to its DIN rail mount and robust type B wide housing, the converter is designed for reliable operation in control cabinets and harsh environments, withstanding temperatures from -40°C to +85°C.

Configuration:

Thanks to the "DALI Console" software on your PC you can:

• Configure and test the DALI network
• Setup the DALI devices including groups, scenes, and IDs
• Verify communication performance before deployment

With the SW67844 software you can additionally:

• Define the parameters of the DALI line and optimize addressing
• Configure Modbus TCP communication parameters
• Update and maintain the device firmware for long-term stability

These tools simplify integration in both new installations and retrofit projects, ensuring maximum compatibility with industrial automation and BMS solutions.

Thanks to its features, the HD67844-B2 is widely used in smart building automation, airports, tunnels, and industrial halls, where centralized control of DALI-based lighting via Modbus TCP is required. The possibility of configuring DALI groups and scenes gives facility managers flexibility in adapting light intensity, scheduling, or energy efficiency strategies. At the same time, Modbus supervisory systems can monitor device status, detect failures, and send commands in real time.
