RIA452 Process indicator with pump control Digital process meter in panel mounted housing for monitoring and displaying analog measured values F 7-digit 14-segment LC display, large bar graph with overrange and underrange Digital status inputs for pump monitoring Flow measurement for open channels and weirs Intrinsically safe input with integrated loop power supply Min/Max value saved Linearization table with up to 32 support points Input 1 x analog (U, I, RTD, TC, R) Output 1 x analog (U, I) 1 x transmitter power supply Output 1 x analog (U, I) 1 x transmitter power supply Display LCD multicolour Illuminated Bargraph Power Supply 90...250 V AC 20...28 V AC 20...36 V DC More information and current pricing: www.endress.com/RIA452 Field of application: The process meter monitors and displays the analog measured values. Pumps can be monitored with the digital status inputs. The RIA452 can provide power directly to two-wire sensors connected. Up to eight freely programmable relays monitor the measured value. Other operating modes for the relays include sensor or device malfunction, batch and pump control functions. Furthermore, the RIA452 can be used as a preset counter and for measuring flow at open channels and measuring weirs.
