DPM-105

Universal Digital
Panel Meter

The DPM-105™ displays speed,
temperature, rate, or virtually any
variable type, in corresponding
engineering units. 0–1 mA input
only . Replaces analog panel meters
for greater accuracy, readability,
and reliability. Use as readout for
Dynalco speed and temperature
transmitters, and as a remote
tachometer.

Instrumentation & Controls

z Universal, Field-Adjustable:

Adjustable readout ranges from zero to
1999, with integral multi-turn span
potentiometer.

FEATURES

z Rugged: No meter movement; all

solid-state. Standard SAE case fits
panels with 3-3/8" openings.

z Sealed: Resistant to sour gas and

moisture that attack springs in an analog
meter movement.

z Large 0.4" High Digits: Liquid Crystal

Display, 1-digit resolution. Display
contrast increases with increasing
ambient light. Ideal for outdoor
installations.

z Third Party Approvals: (Intrinsic Safety)

CSA: Class I, Division 1, Groups A, B, C,
& D, rated 8–40 Vdc, 10 mA maximum.
Meets standards for intrinsic safety, when
connected to CSA certified Zener barrier
devices per Dynalco drawing B8008843.

ABS: Certificate No. 92-QE-10237-X.

z Auto Zero: Readout is “0000” at zero

input with power applied. The unit can be
calibrated from 0 to any display range up
to 1999. The meter indicates negative
only when the signal goes negative.
Positive and negative read-outs follow
the polarity of the input signal.

z Power: Can be powered from 8 to

40 Vdc. Consumes only 0.5 mA at 9 V.

z Signal:Accepts grounded and un-

grounded signal sources.

SPECIFICATIONS

Display: 3½ active digits, optional fixed

zero for 4½ digit display; optional decimal
point after first, second, or third digit. Fixed
zero and optional decimal point and fixed
zero set by internal component board
switch.

Span Adjust: Twenty-five turn
potentiometer permits adjustment of the
display to any desired span from zero to
1999 (3½ digits). A fifth digit (dummy zero)
can be turned on for readouts up to 19990
(4½ digits).
