HD67G06-2-B2 RS232 Modbus Master to HTTP/REST Server Converter

HD67G06-2-B2 is an industrial Modbus Master / HTTP/REST Server converter with RS232 port for integrating serial devices with Ethernet communication.

HD67G06-2-B2 is designed for applications where devices communicating through RS232 and operating as Modbus Master must exchange data with systems using HTTP/REST Server communication. It is a practical solution for industrial integration, retrofit projects, and communication bridging between serial equipment and Ethernet-based applications.

Thanks to its compact Housing type B, DIN rail mounting, and wide power supply range, this converter is well suited for control cabinets, industrial automation systems, monitoring applications, and installations where reliable communication and easy deployment are required. The Ethernet port can be used both for device programming and for HTTP/REST Server communication, which simplifies installation and day-to-day operation.

HD67G06-2-B2 in industrial communication systems.

This model can be used wherever a supervisory system, software platform, or Ethernet application needs access to data from serial devices without creating complex custom middleware. HD67G06-2-B2 helps organize communication between RS232 field devices and an HTTP/REST Server environment, which is especially useful when integrating existing serial equipment into modern Ethernet infrastructures.

An important advantage of the device is the electrical isolation between Ethernet and Power Supply, which improves reliability in industrial environments. The wide operating temperature range and standard 35 mm DIN Rail mounting also make this converter suitable for continuous-duty installations in demanding operating conditions.
