80 Pressure transmitters Adjustable display range Type series AZ Digital display, plugs onto transmitter AZ 331 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 , cm 3 (volume) etc. Technical data Display 3 1/2 digit LED display, 7 mm high, adjustable display range: –50 to +1999 Supply voltage 24 VAC or 24 VDC. Via ribbon cable from the basic module Signal voltage (input) 0–10 V. Signal input via ribbon cable from the evaluation module or from other modules. Signal input switchable with slide switch 9. Normal setting: D (output signal from evaluation module is displayed) Decimal point Set with slide switch Factory setting Input signal 0–10 V 0–10.00 ± 1 digit Power consumption Max. 1 W Degree of IP 65, in the installed protection state Dimensions Height: 1 module unit = 34 mm 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.
