5531
Loop-powered LCD indicator
∙ 4 digit 1/8 DIN (48 x 96 mm) loop-powered LCD display
∙ Easy push-button configuration
∙ Backlit LCD display is readable in low light conditions
∙ Display can be mounted in the safe or Ex area
∙ Available with the 8501 field enclosure
Application
•The 5531 indicator is powered by the 4 to 20 mA
current loop and is easily scaled to display the
correct process value.
•Because it does not require separate power wiring,
the 5531 is perfect for remote display of process
loops.
•The 5531A display can be panel mounted in the
safe area or Ex Zone 2 (gas).
•The 5531B1 Ex display includes the 8501 enclosure
and can be mounted in Ex Zone 2 or 22 (gas or
dust).
•The 5531B2 includes the 8501 enclosure, and can
be mounted in Ex Zone 1, 2, 21 or 22 (gas or dust).
Technical characteristics
•With a full measurement range of 3.6 to 23 mA, the
5531 is NAMUR NE43 compliant.
•The display can be push-button scaled to any range
between -9999 to 9999, and reverse display action
is possible.
•The LCD backlight can be set to half or full intensity
for easy viewing in low light conditions.
•The display only requires 1.5 VDC, (75 Ω loop load),
with the backlight turned off.
•The input is HART® transparent.
•The front push-buttons can be disabled to prevent
unauthorized adjustment.
Mounting / installation
•Once panel mounted with the included gasket, the
5531 provides IP65 ingress protection.
