HD67G05-5-B2 Modbus Master to HTTP/REST Client converter RS485

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

HD67G05-5-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 network-based data exchange services.

By combining an RS485 interface and an RJ45 Ethernet port, the device can act as an efficient communication bridge between industrial installations, building automation systems, telemetry environments and supervisory applications that require access to data through HTTP/REST Client. It is a practical solution for projects where existing Modbus devices must be linked with modern upper-level platforms, web-based applications and integration environments.

HD67G05-5-B2 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 reliability in control cabinets and continuous-duty industrial installations.

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.
