4. SYSTEM DESIGN FOR USE IN
HAZARDOUS AREAS
BR323AL and BR323SS indicators may be
connected in series with any 4/20mA current loop
having a maximum supply voltage of 30V dc and a
maximum current of less than 110mA. It is only
necessary to ensure that the loop can support the
additional 2.3V drop introduced by the indicator.
Fig 4 illustrates a typical application in which a
BR323AL or BR323SS indicator is connected in
series with a 2-wire transmitter and calibrated to
display the measured variable or control signal in
engineering units.
