HD67G03-5-G43-B2 RS485 to HTTP/REST client converter with LTE

HD67G03-5-G43-B2 connects RS485 devices with HTTP/REST client communication through LAN and SIM LTE.

HD67G03-5-G43-B2 is an industrial RS485 / HTTP/REST Client - Converter designed to integrate devices communicating through RS485 with modern systems based on HTTP/REST client communication. This model works well in telemetry applications, remote monitoring systems, industrial automation, and integration projects where classic serial communication must be connected with Ethernet infrastructure and web-based services. :contentReference[oaicite:0]{index=0}

The HD67G03-5-G43-B2 variant offers LAN and SIM LTE connectivity, which allows the device to operate both in a local Ethernet network and in distributed installations where remote data access is required. This makes it a practical solution for system integrators, machine builders, and maintenance teams that need to connect field devices with higher-level platforms without creating a complex intermediate communication layer. :contentReference[oaicite:1]{index=1}

HD67G03-5-G43-B2 allows precise configuration of HTTP/REST 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 statuses, alarms, or other process information to a supervisory system. :contentReference[oaicite:2]{index=2}

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 helps maintain stable operation in industrial environments. The compact housing type B, 35 mm DIN rail mounting, and wide operating temperature range from -40°C to +85°C make this model suitable for demanding industrial installations. :contentReference[oaicite:3]{index=3}

In the G43 version, the manufacturer uses an LTE module with Micro-SIM support and an SMA Female antenna connector. For RS485 communication, line termination with a 120 Ω resistor is also supported, which helps ensure correct bus transmission and improves communication stability in extended installations. :contentReference[oaicite:4]{index=4}
