HD67421-E4R CANopen to Modbus RTU Master converter – IP67, metal housing, 4kV isolatio

Industrial CANopen to Modbus RTU (RS485) master converter, metal housing resistant to vibration and shock with triple 4kV isolation between CANopen/Modbus RTU Master, CANopen/power supply and Modbus RTU Master/power supply, IP67

Particularly suitable for installation in cars, trucks, trains, boats, in the industrial sector and in fragile environments. The robust metal housing ensures mechanical durability even under constant vibration or shocks typical of automotive and railway applications. The high resistance makes it a reliable choice for long-term deployment in demanding transport and marine systems, where mechanical stress is unavoidable. Its triple 4kV galvanic isolation guarantees a secure barrier between power supply and communication buses, protecting sensitive electronics. The IP67 protection ensures full sealing against dust and temporary immersion in water, allowing outdoor use. These properties make the converter indispensable in mission-critical projects where continuous communication and safety are essential. It can be integrated into advanced control systems, ensuring reliability across industrial automation and automotive sectors. Such features also reduce maintenance intervals, lowering total cost of ownership for integrators.

Two versions, one with a PCB coating (suffix code V) that ensures total protection against dust (IP65) and another resin encapsulation-based version (suffix code R) which gives the device IP67 high performance insulation for wet environments and resistance to electromagnetic noise. The V version is recommended for general industrial installations, where moderate dust protection is sufficient. The R version, thanks to its resin sealing, is ideal for marine, outdoor and heavy-duty environments. Encapsulation increases long-term stability and prevents condensation issues inside the housing. This dual offering provides integrators with flexibility to choose the right model for their application. Both variants maintain full functionality and communication performance. The difference lies only in mechanical and environmental protection. Thus, the HD67421 family can adapt to projects ranging from indoor factories to offshore platforms.

This product can be mounted on any type of surface (horizontal, vertical or oblique) with four fixing lugs. Mounting flexibility allows installation in vehicles, control cabinets, ships or directly on industrial machinery. It is also possible to secure the device using metal hose clamps, providing an alternative where drilling or standard fixing is not possible. Such adaptability is especially valuable in mobile applications, where space is limited and vibrations are constant. Users can choose the type of connector: Mini-Fit® or Superseal 1.5®, depending on their environmental needs. Mini-Fit® is more compact and often used in indoor environments, while Superseal 1.5® provides a superior seal for automotive and outdoor usage. This ensures that connections remain stable even under high humidity or vibration. As a result, the HD67421-E4R can be precisely adapted to the needs of diverse industries.

Excellent operating temperature range from -40°C to +105°C fully meets the standards of the AUTOMOTIVE sector. This allows the device to function reliably in freezing outdoor conditions as well as in hot engine compartments. Such a wide range makes the product suitable for use in railways, maritime, renewable energy and industrial automation. It also means integrators do not need additional cooling or heating for the converter, reducing system costs. The built-in microprocessor optimizes data processing and guarantees stable communication between networks. This improves response times in real-time applications like safety monitoring or energy management. By combining robustness, intelligence and reliability, the HD67421 becomes a long-term solution for critical infrastructures. The high standards of design ensure compliance with the requirements of professional automation projects worldwide.
