HD67G03-5-B2 RS485 to HTTP/REST client converter for Ethernet communication

HD67G03-5-B2 connects RS485 devices with HTTP/REST client communication in Ethernet networks.

HD67G03-5-B2 is an industrial RS485 to HTTP/REST client converter, designed to integrate devices communicating via RS485 with modern data exchange systems based on HTTP/REST. This model works well in applications where serial communication must be connected with Ethernet infrastructure and network services used by higher-level systems.

The HD67G03-5-B2 variant has been designed for operation in an Ethernet network, which means it can be easily deployed in control cabinets, telemetry systems, industrial installations, and integration projects where structured, stable, and predictable communication is essential. It is a practical solution for system integrators, machine builders, and maintenance teams who want to connect field devices with network services without using a complex intermediate infrastructure.

HD67G03-5-B2 allows precise configuration of HTTP/REST communication parameters, serial line parameters, the list of servers, and communication endpoints. As a result, the converter can be adapted to a specific application, whether its task is to transfer measurement data, operating states, alarms, or other process information to a higher-level system.

The device supports RS485 data rates up to 115200 bps and 10/100 Base-T Autosensing Ethernet communication. An additional advantage is the electrical isolation between Ethernet and power supply, which supports stable operation in industrial environments. The compact housing type B, mounting on a 35 mm DIN rail, and wide operating temperature range from -40°C to +85°C make this model suitable for demanding industrial installations.

For RS485 communication, the manufacturer provides the possibility of terminating the line with a 120 Ω resistor, and the maximum cable length can reach 1200 m. This is important in distributed installations where transmission reliability and correct bus termination have a significant impact on the stability of the whole system.
