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 5531B can be mounted in Ex Zone 1.
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.
