HD67508-A1-485 Modbus TCP Slave to Modbus Master converter with dual Ethernet ports

Industrial Modbus TCP Slave to Modbus Master converter with two Ethernet ports, housing type A (slim), DIN rail mount.

The HD67508-A1-485 is a professional gateway for Modbus integration, designed to connect multiple Modbus RTU Slave devices to a Modbus TCP Master via Ethernet. With its dual Ethernet ports, the device integrates seamlessly into industrial networks, supporting series connection of several Ethernet-based devices without the need for an external switch. Its slim housing type A and DIN rail mounting make it suitable for compact industrial panels. The converter is particularly valuable in Industrial Automation Systems (IAS) and Building Management Systems (BMS), where robust and secure communication is essential. Thanks to its free SW67508 software, configuration is straightforward, even for complex installations.

Configuration

Configuration of the HD67508-A1-485 is carried out using the SW67508 software, a free PC application that simplifies commissioning. Through this tool, users can set parameters for both Modbus TCP communication and the Modbus RTU serial line, ensuring compatibility with a wide range of devices. The software also allows for firmware updates, extending the lifespan and adaptability of the converter. Even complex addressing schemes and network hierarchies can be managed intuitively, reducing deployment times. In practice, the configuration interface ensures that even large Modbus RTU networks can be integrated quickly with Ethernet-based supervisory systems.

• Define Modbus TCP line parameters
• Set Modbus RTU serial communication parameters
• Perform firmware updates

Features

The device integrates advanced safety and flexibility features, making it highly reliable in demanding environments. It includes triple isolation between RS232/RS485–Power Supply, RS232/RS485–Ethernet, and Power Supply–Ethernet, ensuring protection against electrical disturbances. The internal Ethernet switch allows cascading of devices, eliminating the need for an additional external switch. Supporting 10/100Base-T autosensing, the converter adapts automatically to network conditions. The rugged DIN rail mount design ensures long-term mechanical stability, while its wide temperature range from -40°C to +85°C guarantees operation in harsh industrial environments.

• Triple isolation between communication and power lines
• Integrated Ethernet switch for cascading connections
• 10Base-T / 100Base-T autosensing for Modbus TCP
• Compact housing type A, DIN rail mount

Applications

The HD67508-A1-485 finds application in a wide variety of automation projects. In industrial plants, it connects legacy Modbus RTU Slave equipment such as sensors, actuators, and controllers to modern Ethernet-based supervisory systems. In BMS installations, it integrates HVAC systems, energy meters, and environmental monitoring devices into central management platforms. The wide temperature range and robust design allow use in outdoor cabinets, transport systems, and harsh industrial sites. Thanks to its compact size and cascading Ethernet feature, it is particularly suited for installations where multiple devices need to be connected in limited space, such as machine control panels or distributed control systems.
