1. Measurement principle: The RIA15 loop indicator is installed in a 4 - 20 mA or HART® signal loop to digitally transmit the measurement signal or HART® process variable. Loop display instrument without external power supply, directly powered by the loop. The device complies with HART® communication protocol requirements and can be used with HART®5.0 and above. The LCD display can display a 5-digit expandable measurement value, which can be easily read by the user even in strong light conditions. In addition to displaying measured values, units and bar graphs can be easily displayed with three keys. A device with a backlight display function can be selected as desired. However, the voltage drop will increase. RIA15 can be used with specified models of E H sensors or transmitters, which can not only display measured values, but also perform sensor settings. However, the option Level or Analysis must be selected in the ordering options ".
2. The distribution of power supply terminals is shown in the following figure: Note that the instrument should be connected in series with RIA15.
