Dwyer Instruments DPMA-4 Series Installation And Operating Instructions

Series DPMA-4 Adjustable LCD Digital Panel Meter offers a
3-1/2 digit display for easy viewing in a standard 1/8 DIN package.
Unit accepts 4-20 mA DC inputs with a wide bipolar zero and span
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 24 VDC power
supply is required for the operation of the backlight.
INSTALLATION
The Series DPMA-4 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
The unit is powered by a 4-20 mA loop and the screw terminal for
wiring is located on the back of the adder board marked with +
SIG -. The backlighting requires a 24 VDC power supply and
should be connected to terminals identified with +pwr-.
