Note: For information on the intrinsically safe cabling for PR-23-...-IA, see Sec-
tion 9.11.2 on page 140.
320x240 pixel graphical LCD with LED backlight
18 membrane keys
Two independent current sources, 4-20 mA, max.
load 1000 Ohm, galvanic isolation 1500 VDC or AC
(peak), hold function during prism wash
AC input 100-240 VAC, ±10%, 50/60 Hz/30 VA,
optional 24 VDC, Overvoltage Category II, Pollution

Two built-in signal relays, max. 250 V/3 A
Four switch inputs.
Two current outputs configurable independently to
indicate process concentration or temperature of
either sensor.
One or two sensors can be connected to the
transmitter. Sensors independent of each other:
own parameter sets and usable in different
applications.
Only one sensor can be connected to the transmitter.
Used with the Intrinsically safe sensor PR-23-...-IA.
