Low-Power Edge GatewayBuilt for sensor data acquisition, transmission and management in low-power scenariosThe USR-SC150 is a newly launched DIN-rail 4G edge gateway designed for low-power scenarios. It features advanced low-power operation logic for genuine power saving, and can be connected to a solar photovoltaic power supply system to ensure stable operation even during continuous rainy weather. Built to industrial design standards, it supports wide-voltage terminal power input, DI/AI/485 data acquisition, and offers simple configuration.
Key Applications at a Glance

  • Supports 2-channel 4-20mA analog, 1-channel DI acquisition and 1 RS485 interface for full data collection of various instruments
  • Supports polling acquisition, realizes Modbus RTU to JSON reporting, and completes local data logic processing
  • Supports mainstream cloud platforms such as Azure and AWS, compatible with standard MQTT/TCP protocols
Sensor Power Supply & AcquisitionProvides power interface for sensors, cuts off power during sleep to minimize overall power consumption.
Outdoor Solar-Powered Longevity

  • Ideal for outdoor solar-powered scenarios,long-endurance applications in continuous rainy weather
  • Adopts low-power operation logic with timed wake-up,Power on before acquisition, power off after acquisition
  • Flexible mode adjustment via DIP switches
Multiple Data Acquisition Interfaces

  • Supports 2-channel 4-20mA analog, 1-channel digital input, and 1 RS485 data acquisition.
  • Compatible with mainstream sensors on the market to meet diverse user needs.
  • Standard Modbus-RTU Supported.
Edge Acquisition & JSON Reporting

  • Pre-configured Modbus RTU data points, edge computing, and custom JSON format reporting for easy access to TCP/MQTT private cloud platforms.
  • Supports 4G Cat.1 network standard，Stable operation from -25°C to 75°C.
Offline Caching & Resumable Transmissio

  • Stores up to 1200 data records internally, expandable via external TF card.
  • When network is abnormal, data is stored in cache and retransmitted to the platform after reconnection.
Cloud-Based Remote O&MQuickly connect to the cloud via QR code for remote parameter configuration, firmware upgrades, and other operations on gateways anytime, anywhere. Eliminates on-site business trips and reduces labor costs.
