HD67G06-5-G43-VPN-B2 Modbus Master to HTTP/REST Server converter with LTE

HD67G06-5-G43-VPN-B2 connects Modbus Master RS485 devices with HTTP/REST Server communication via Ethernet, SIM LTE and VPN service.

HD67G06-5-G43-VPN-B2 is an industrial ADFweb converter designed to connect devices operating as Modbus Master on the RS485 side with modern systems and applications based on HTTP/REST Server communication. This model is a practical solution wherever classic Modbus communication must be integrated with Ethernet infrastructure and secure remote access over a mobile network.

The HD67G06-5-G43-VPN-B2 variant offers LAN + SIM LTE connectivity together with VPN Service, making it a strong choice for applications that require both stable data exchange between Modbus Master RS485 devices and an HTTP/REST Server environment, as well as safer remote access to distributed industrial systems. It fits well in automation projects, telemetry installations, building automation systems and service environments where communication reliability matters.

The device is designed for industrial operation. It offers a wide power supply range of 8..24V AC / 12..35V DC, an operating temperature range of -40°C to +85°C, compact housing type B and DIN rail mounting. These features make the converter suitable both for new installations and for upgrades of existing control cabinets and automation systems.

On the communication side, the unit combines an RS485 serial interface with an RJ45 Ethernet port and SIM LTE access, allowing it to work in locations where wired infrastructure is limited or where remote connectivity is required. With 10/100 Base-T Autosensing on the Ethernet side and data rates up to 115200 bps on the serial side, the converter can be integrated into many industrial data exchange scenarios.

Configuration is carried out using SW67G06, which allows the user to set communication parameters and adapt the device to the requirements of a specific industrial application. This makes HD67G06-5-G43-VPN-B2 a flexible solution for projects that combine Modbus Master, RS485, Ethernet and remote HTTP/REST-based data exchange.
