Field or panel indicator for 4 to 20 mA or HART ® process values. The loop-powered process indicator RIA15 displays 4 to 20 mA measured values or optionally up to four of a sensor's HART® process variables in all industries. The RIA15 has 5-digit measured value display with 17 mm (0.67 in) digit height with dimension, bar graph and activatable backlighting and can be use for panel-mount housing or field housing as local display. The Endress+Hausers process indicator is available with 4 to 20 mA with a version up to 4 measured values of one sensor can be indicated in alternation. The indicator can be set as primary or secondary HART master and actively inquire the values from the sensor. Scalable display value Easy 3-key operation for configuring the device No external power supply required Key Benefits Easy configuration and on-site parameter setup with 3 front-mounted key push buttons. No external power supply is necessary, the device is powered directly from current loop. Perfect solution if measuring points are difficult to access, especially if long wiring distances are required / Voltage drop < 1V Interrogates up to 4 different measurement values in a running process and displays them (via HART protocol).
