Series DPMA-5 Adjustable Panel Meter offers a large 1˝, 3-1/2 digit
display for easy viewing in a standard 1/8 DIN package. Unit accepts
voltage inputs with a wide bipolar span and zero adjustment. Standard
features include field selectable engineering units and decimal point
positions. Choose from red, amber, or green segments for easy viewing
at a distance. A separate 24 VDC power supply is required for the
operation of the backlight.
INSTALLATION
The Series DPMA-5 is designed to snap into a 3.62˝ (92 mm) W x 1.77˝
(45 mm) H panel cutout. No additional hardware is required.
WIRING
Three sets of jumper pins are located on the back of the meter. Move
the jumper to fit over the appropriate pins which correspond to the
desired signal input voltage, supply voltage and decimal point position.
An external 12 or 24 VDC power supply is required to power the meter
and should be connected to the screw terminal marked with “+pwr-” (see
Figure 2). The backlighting requires a separate 24 VDC power supply
and should be connected to terminals identified with “+B/L-”.
