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), m3, 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.
