DPM500SL-20 Datasheet, PDF (1/2 Pages) List of Unclassifed Manufacturers – 12.5mm (0.5“) Digit Height

DPM 500
3½ Digit LCD Module
The DPM 500 uses advanced components and construction techniques to provide a uniquely compact unit. The meter is in a 40 pin
DIL integrated circuit format that can be plugged directly into a DIL socket or panel mounted using the snap in bezel. For single rail use,
the DPM 500S-BL features a built in negative rail generator, enabling the meter to measure a signal referenced to its own power supply
0V.

SCALING
Two resistors Ra and Rb may be fitted in order to alter the
full scale reading (F.S.R.) of the meter - see table.
Meter will need re-calibration.

SAFETY
METHOD
40 Pin DIL IC Socket
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 exceed 60Vdc, then fit scaling resistors externally to the module. The user must ensure that the incorporation of the
DPM into the user’s equipment conforms to the relevant sections of BS EN 61010 (Safety Requirements for Electrical Equipment for
Measuring, Control and Laboratory Use).

PANEL FITTING
REAR VIEW
Fit the bezel to the front of the panel and locate the meter into the bezel from behind. Alternatively the meter and bezel may be assembled before
fitting to the front of the panel but care must be taken not to use excessive force. Finally fit the window into the front of the bezel.
