USR-DR154 - 4G RS485 Gateway - PUSR

4G to RS485 and Modbus RTU/TCP Industrial Gateway

The PUSR USR-DR154 is an ultra-compact 4G Cat 1 gateway designed to connect RS485 equipment to the cellular network. It allows serial equipment to be quickly transformed into a connected IoT device, without replacing the existing installation.

4G to RS485 Gateway

The USR-DR154 supports 4G LTE Cat 1 connectivity with a physical SIM slot. It is designed for applications such as telemetry, supervision, automation, energy, connected agriculture, and remote equipment management.

Modbus RTU to Modbus TCP Conversion

The gateway integrates Modbus RTU to Modbus TCP conversion, facilitating remote access to serial industrial equipment. It also supports network protocols such as TCP, UDP, HTTP, and MQTT for data uplink.

Ultra-Compact Form Factor

With its small form factor, DIN rail mounting, and 5-24 VDC power supply, the USR-DR154 easily integrates into cramped cabinets, field enclosures, or embedded installations.

Industrial Applications

The USR-DR154 is suitable for environmental monitoring, irrigation, smart grid, meters, inverters, charging stations, remote pump management, HVAC, or SCADA supervision via Modbus.
