Modulo con display LED a 3,5

ENGLISH

A compact low-cost LED module ideally suited for applications where a bright display under all
conditions is required. The DPM 40 is fitted with high efficiency LEDs and supplied with a filter
and bezel to give a high contrast display. The small size and low cost of the unit makes it very
suitable for highvolume OEMapplications.

• 11mm (0.43“) Digit Height • Auto-polarity

• Programmable Decimal Points • 200mV d.c Full Scale Reading (F.S.R.)

• Auto-zero • Digital Hold

SCALING

Two resistors maybe used to alter thefull scalereading of themeter -see table.
Note that themeter willhave to bere-calibratedby adjusting thecalibration pot.

SAFETY

To comply with the Low Voltage Directive (LVD 93/68/EEC), input voltages to the module’s pins must not exceed 60Vdc. If
voltages to the measuring inputs do exceed60Vdc, thenfit scaling resistors externally to the module.The usermust ensure that
the incorporationof the DPMinto the user’sequipment conforms tothe relevant sectionsof BSEN 61010 (SafetyRequirements
for Electrical Equipmentfor Measuring, Controland LaboratoryUse).
