Principais características

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 area or in I.S. / Ex zone 2


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 I.S. / Ex Zone 2 (gas).

Once panel mounted with the included gasket, the 5531 provides IP65 ingress protection.


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.
