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

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

HD67G04-5-G43-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 a practical solution wherever a classic serial bus must be integrated with Ethernet infrastructure and remote access through a mobile network.

The HD67G04-5-G43-B2 variant offers LAN + SIM LTE connectivity, which allows it to operate both in local industrial networks and in distributed telemetry installations, building automation systems, supervisory applications and service environments. It is a good choice for system integrators, machine builders and maintenance teams that need a reliable bridge between RS485 communication and an HTTP/REST Server environment.

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 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 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.
