HD67G06-2-G43-E-VPN-B2 RS232 Modbus Master to HTTP/REST Server with VPN and eSIM

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

HD67G06-2-G43-E-VPN-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 provides LAN + SIM LTE + eSIM connectivity together with VPN Service, making it a practical solution for projects that require flexible deployment and secure remote communication.

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, and retrofit projects. The Ethernet port can be used both for device programming and for HTTP/REST Server communication, while the SIM card slot, integrated eSIM, and VPN functionality expand communication possibilities in distributed industrial applications.

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

This model can be used wherever installed serial devices need to be connected with supervisory software, network services, or Ethernet-based data exchange platforms working through HTTP/REST Server. In practical industrial environments, this helps simplify the integration of existing RS232 equipment into modern communication architectures without creating complex custom interfaces.

A major advantage of HD67G06-2-G43-E-VPN-B2 is the combination of LAN + SIM LTE + eSIM with VPN Service. This makes the converter a strong option for remote industrial sites, distributed installations, field applications, and projects where secure service access, stable communication, and flexible mobile connectivity are important.

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