The Series DPML-4 LCD Digital Panel Meter offers a large 4-1/2 digit
LCD display with a choice of red, amber or green segments for easy
viewing at a distance. The meter accepts loop powered 4-20 mA DC
input. Standard features include field engineering units and decimal
point positions. A separate 24 VDC power supply is required for the
operation of the back light.

INSTALLATION
The Series DPML-4 is designed to snap into a 2.4˝ (61 mm) W x 1˝ (25.4
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 + B/L -.
Note: If backlight supply is not loop supply, ground should be referenced
together.
