Simple 3-button operation for parameterisation
Scalable display value
No external power supply required; voltage drop ≤1 V (HART® ≤1,9 V)

Fields of application

Panel mounting or field housing as on-site indication
Use as Primary or Secondary HART® Master.

Details

The RIA15 process indicator from Endress+Hauser is equipped with 4 to 20 mA or with HART® protocol. In the HART® version, up to 4 measured values of one sensor can be displayed alternately on the display. For this purpose the indicator can be set as Primary or Secondary HART® Master and actively query the values. The low voltage drop of < 1 V (< 1.9 V for HART®) proves to be a great advantage in Ex applications where only a limited voltage is usually available.
