HD67G06-2-G43-B2 RS232 Modbus Master to HTTP/REST Server LTE

HD67G06-2-G43-B2 is an industrial Modbus Master / HTTP/REST Server converter with RS232 port and LAN plus SIM LTE connectivity for integrating serial devices with modern network communication.

HD67G06-2-G43-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. This version combines serial communication with Ethernet infrastructure and additionally offers SIM LTE connectivity, making it suitable both for standard LAN environments and for installations where remote mobile communication is required.

With its compact Housing type B, 35 mm DIN Rail mounting, and wide power supply range, this converter is well suited for control cabinets, industrial automation systems, telemetry installations, remote assets, and retrofit projects. The Ethernet port can be used for both device programming and HTTP/REST Server communication, while the LTE module with SIM support increases deployment flexibility in distributed applications.

HD67G06-2-G43-B2 in industrial communication systems.

This model can be used wherever existing serial devices need to be connected with supervisory software, cloud-integrated services, or Ethernet-based platforms working through HTTP/REST Server. In practice, this makes it easier to integrate installed RS232 equipment into more modern communication environments without building complex custom interfaces.

An additional advantage of HD67G06-2-G43-B2 is its LAN + SIM LTE connectivity, which gives greater freedom in projects where fixed network access is limited or unavailable. This makes the converter a practical choice for remote industrial sites, service access scenarios, monitoring systems, and applications that need communication through Ethernet or over a mobile network.

The device also offers electrical isolation between Ethernet and Power Supply, which improves reliability in industrial environments. The wide operating temperature range and DIN rail mounting further support stable operation in demanding conditions.
