Honeywell AZ DATASHEET

Pressure transmitters

Adjustable display range

AZ display modules show the output of a trans­mitter from the MODUFLEX system on an LED
display.
On 3-conductor systems the supply and signal
voltage is led from the evaluation module via rib­bon cable. No additional wiring is needed.
The starting and end values of the display can
be set anywhere between -50 and +1199, so
that any display range can be assigned to any

pressure range. The decimal point can be
moved with a slide switch.
The y-signals of the transmitter can thus be dis­played in any unit, e.g. V, mA, bar, mbar, %,°C,
°F, psi, m, cm (filling level), m

3

, cm3(volume) etc.

By setting the input selector switch 9 to position E, the unit can be made to display signals generated
by other modules. Furthermore, in its condition on delivery (factory setting 0–10.0), the display module
can be used for accurately setting the operating range of a transmitter. All controls are accessible from
the front, after removing the window. After setting, reinsert the window and press it in evenly.
