PANEL CUTOUT FOR
WINDOW MOUNTING
INSTALLATION
The Series DPMW is designed for window mounting in a 2.31˝ (58.4
mm) W x .91˝ (22.9 mm) H panel cutout.
WIRING
The unit is powered by a 4-20 mA loop and the screw terminals for wiring
are 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.
The Series DPMW LCD Digital Panel Meter is designed with a 3-1/2
digit, high contrast LCD display. The colored segments are available in
red, amber, or green - ideal for viewing at a distance. The Series DPMW
features user selectable engineering units, selectable decimal point
position and adjustable zero and span. The meter accepts a 4 to 20 mA
input signal for pressure, level, flow, and temperature transmitter. A 24
VDC power supply is required to illuminate the colored segments. The
series DPMW can be quickly installed in a window cutout.
