The process indicator monitors and displays analog measured values; pump operation can be monitored via digital status inputs. RIA452 can power the connected two-wire sensors. Up to 8 freely programmable relays monitor measured values to prevent upper or lower limits from being exceeded. Other relay operating modes include sensor or instrument fault detection, batching and pump control. In addition, RIA452 can be preset for use as a counter to measure flow in open channels and weirs.

Advantages
7-digit 14-segment LC display, large bar graph for above-range and below-range indication
Digital status input for pump monitoring
Flow measurement in open channels and weirs
Intrinsically safe input with loop power supply
Min/max value storage
Linearization table with up to 32 support points

Application
The single-channel panel meter RIA452 monitors and displays analog measured values. Pumps can be monitored using digital status input signals.
RIA452 can directly power the connected two-wire transmitters, ensuring intrinsically safe operation. Up to 8 freely programmable relays monitor measured values to prevent limit values from being exceeded or undershot. Other relay operating modes include detecting sensor or device faults, batching and pump control functions (e.g. alternating pump control).
