  • Page 10: Product Overview

    Product Overview 4-1 Main Features Rotating Shadow Band and Pyranometer  The RSB-02 digitally controls the rotation of a motor-driven shadow band to periodically block light from a pyranometer (MS-80S/SH). This enables accurate measurement of Global Horizontal Irradiance (GHI), Diffuse Horizontal Irradiance (DHI), and Direct Normal Irradiance (DNI) which are traditionally measured using a tracking method.

  • Page 12: Working Modes

    4-3 Working modes The RSB-02 measures GHI and DHI, and calculates DNI, by moving the shadow band to shade the pyranometer and measuring the irradiance when shaded. The RSB-02 has two working modes that employ different measurement methods. You also have the option to add another pyranometer.

  • Page 13: System Configuration

    Product Overview 4-4 System Configuration The measurement system is made up of the RSB-02, C-BOX, and pyranometer. Measured values are collected by the data logger using RS485 (Modbus RTU) communication. The equipment can be configured from a PC using RS-485 (Modbus RTU) communication. Equipment configuration can be performed by connecting the C-BOX to a PC using RS-485 (Modbus RTU) communication.
