HD67G05-5-G43-B2 Modbus Master to HTTP/REST Client converter with LTE

HD67G05-5-G43-B2 connects Modbus Master RS485 devices with HTTP/REST Client communication via Ethernet and SIM LTE.

HD67G05-5-G43-B2 is an industrial ADFweb converter designed to connect devices operating as Modbus Master on the RS485 serial side with modern systems and applications based on HTTP/REST Client communication. This model is well suited wherever a classic serial bus must be integrated with Ethernet infrastructure and remote access over a mobile network.

The HD67G05-5-G43-B2 variant offers LAN + SIM LTE connectivity, allowing it to operate both in local industrial networks and in distributed telemetry installations, building automation environments, supervisory systems and service applications. It is a practical solution for system integrators, machine builders and maintenance teams that need a reliable bridge between Modbus Master RS485 communication and an HTTP/REST Client environment.

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, 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, 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 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.
