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).
