Field of Application

The single-channel panel meter RIA452 monitors and displays analog measured values. Pumps can be monitored with the digital status inputs.

The RIA452 can provide power directly to two-wire transmitters connected, intrinsically safe as an option. Up to eight freely programmable relays monitor the measured value for limit value overshoot and undershoot. Other operating modes for the relays include sensor or device malfunction, batch and pump control functions (e.g. alternating pump control).
