HD67G04-5-B2 RS485 to HTTP/REST Server converter

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

HD67G04-5-B2 is an industrial ADFweb converter designed to connect RS485 devices with modern systems and applications based on HTTP/REST Server communication. This model is a practical solution wherever a serial network must be integrated with Ethernet infrastructure and IP-based data exchange.

By combining an RS485 interface with an RJ45 Ethernet port, the device acts as an effective communication bridge between industrial installations, building automation systems, telemetry applications and supervisory environments that require access to serial data through HTTP/REST Server. It is well suited for projects where existing field devices must be integrated with modern control or monitoring platforms.

HD67G04-5-B2 is built 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 additional advantage is the electrical isolation between Ethernet and power supply, which supports reliable integration inside control cabinets and demanding 24/7 industrial applications.

For the RS485 line, the manufacturer provides the option to enable 120Ω termination via DIP-switch, which simplifies proper implementation 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.
