Industrial IoT gateway equipped with 2 RS485 ports, an RJ45 Ethernet port, and Edge Computing, protocol conversion, and local SD card data buffering capabilities. It enables data acquisition from Modbus RTU, Modbus TCP, and DL/T645-2007 devices, local data processing, and secure transmission to cloud platforms via MQTT or TCP protocols with SSL encryption support. USR-N720-ETH Edge IoT Gateway
The USR-N720-ETH Edge IoT Gateway is designed to integrate industrial automation equipment with IoT systems and cloud platforms. The device provides data acquisition, local information processing (Edge Computing), communication protocol conversion, and secure data transmission to IoT servers and cloud services. The ETH version communicates exclusively through its Ethernet interface.
The gateway supports Modbus RTU, Modbus TCP, and DL/T645-2007 protocols, allowing data conversion to JSON format and transmission via MQTT or TCP. The integrated Edge Computing engine supports up to 1000 data points, enabling local mathematical operations, data analysis, and filtering before sending information to the server. This approach reduces cloud infrastructure workload and shortens system response times.
The gateway can also operate as a Modbus RTU ↔ Modbus TCP protocol converter, allowing communication between serial devices and PLC systems, SCADA platforms, or private monitoring servers.


The USR-N720-ETH features two RS485 ports and one RJ45 Ethernet port for LAN connectivity. The device supports up to 5 simultaneous independent connections, including 2 MQTT connections, 2 TCP connections, and 1 PUSR Cloud connection. SSL encryption is available for both MQTT and TCP communications to ensure secure data transmission.
The integrated SD card slot enables local data buffering during Internet outages. Once the connection is restored, cached data is automatically transmitted to the server. The gateway also supports remote management through the PUSR Cloud platform, allowing users to configure parameters, update firmware, and monitor device status remotely.
The device is designed for operation in demanding industrial environments. Its metal enclosure improves heat dissipation, while the 9–36 V DC wide input voltage range simplifies integration with industrial automation systems. A hardware and software watchdog further enhances operational reliability. The gateway operates within a temperature range of -40°C to +85°C, provides high EMC immunity, and supports DIN rail or wall mounting.

The gateway is suitable for applications including smart factories, energy monitoring systems, utility monitoring, building automation, smart agriculture, and IoT installations requiring local edge data processing.
