HD67G04-5-G43-VPN-B2 RS485 to HTTP/REST Server converter with LTE and VPN

HD67G04-5-G43-VPN-B2 connects RS485 devices with HTTP/REST Server communication via Ethernet, SIM LTE and VPN service.

HD67G04-5-G43-VPN-B2 is an industrial ADFweb converter designed to connect devices communicating via RS485 with modern systems and applications based on HTTP/REST Server. This model is intended for installations where a classic serial bus must be integrated with Ethernet infrastructure and secure remote access through a mobile network.

The HD67G04-5-G43-VPN-B2 variant offers LAN + SIM LTE connectivity together with VPN Service, making it a strong choice for applications that require both reliable data exchange between RS485 devices and HTTP/REST Server environments and more secure remote access to distributed industrial systems. It is well suited 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 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 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 24/7 installations.

On the mobile side, this model uses an LTE module with SIM card support, which extends deployment possibilities in locations where fixed wired infrastructure is unavailable or where stable 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.

For the RS485 line, the manufacturer provides the option to enable 120Ω termination via DIP-switch, which helps ensure correct commissioning in typical industrial topologies. Configuration is carried out using SW67G04, which allows the user to configure HTTP/REST Server parameters, serial line settings, clients and endpoints, and to update the device firmware.
