HD67G05-2-G43-E-VPN-B2 Modbus Master to HTTP/REST Client converter with LTE, eSIM and VPN

HD67G05-2-G43-E-VPN-B2 connects Modbus Master RS232 devices with HTTP/REST Client communication via Ethernet, SIM LTE, eSIM and VPN service.

HD67G05-2-G43-E-VPN-B2 is an industrial ADFweb converter designed to connect devices operating as Modbus Master on the RS232 serial side with modern systems and applications based on HTTP/REST Client communication. This model is well suited wherever classic serial communication must be integrated with Ethernet infrastructure and secure remote access over a mobile network.

The HD67G05-2-G43-E-VPN-B2 variant offers LAN + SIM LTE + eSIM connectivity together with VPN Service, making it a strong choice for applications that require both reliable data exchange between Modbus Master RS232 devices and HTTP/REST Client environments and more secure remote access to distributed industrial systems. It is a practical solution for automation integrators, machine builders, telemetry projects, building automation and multi-site industrial installations.

The device is designed for industrial operation. It offers a wide 8..24V AC / 12..35V DC power supply range, an operating temperature range of -40°C to +85°C, compact housing type B and 35 mm DIN rail mounting. An important advantage is also the electrical isolation between Ethernet and power supply, which improves safety and reliability in control cabinets and continuous-duty industrial installations.

On the mobile side, this model uses an LTE module with SIM card support and integrated eSIM, which extends deployment possibilities in locations where fixed wired infrastructure is unavailable or where stable and flexible remote access to process data is required. Combined with the RJ45 port and 10/100 Base-T Autosensing communication, the converter fits well into modern automation, monitoring and telemetry systems.

Configuration is carried out using SW67G05, which allows the user to define HTTP/REST parameters, configure the Modbus line, define the list of HTTP/REST servers for Modbus communication, configure endpoints and update the device. This makes it possible to adapt the converter precisely to the needs of a specific industrial application.
