Analog measured values are displayed, evaluated and calculated by the process meter. Two-wire sensors can be loop-powered. The universal input can connect current, voltage, RTDs and TCs. Limit values can be monitored and relays can be switched. Process signals can be transmitted via the analog output. A color change in the event of a fault supports alarm recognition. The built-in “differential pressure” application package enables fast and simple commissioning of different pressures.
Advantages
5-digit 7-segment measured value display with LC backlighting
1 or 2 universal inputs
2 relays (optional)
Min/max value memory
1 or 2 calculated values and linearization tables
Digital status output (open collector)
SIL2 approval (optional)
Application areas
The RIA46 panel meter provides display functions for analog input of process and status signals, analog or digital signal output and interface configuration. The connected sensors can be powered by the integrated LPS. All measured and calculated values can be used as independent signal sources for display, output, transmission and interface communication.
