The DP460 Series is designed for
a variety of temperature, current,
voltage, strain gage and load cell
measuring applications. Excellent
accuracy and small size combine
to make it the ideal choice for most
industrial indications.
The DP460-T and DP460-RTD
temperature models feature a unique
0.1° or 1° automatic resolution
(unless the instrument is programmed
to display 1° only). Select among nine
temperature sensors or thermocouple
types, J, K, T, E, R, S, and B or 100
ohm; 3-wire, Platinum RTD’s for
either 0.00385 or 0.00392 alpha.
Behind the snap-off lens, each of
these nine thermocouples can be
selected via a miniature rotary switch.
No calibration is required to switch
between thermocouple types. Another
miniature DIP switch selects between
°F or °C display.
The DP460-V voltage models allow
selection between mA or voltage input
with a switch easily accessible behind
the snap-off front lens. Full scales are
0 to 20 mA or 0 to 10 V. These or any
subset (e.g., 4 to 20 mA, 1 to 5 V) can
be scaled. Two simple pushbuttons
conveniently located behind the snapoff lens are used to set zero (Lo), full
scale (Hi) and a decimal point. The
indicator can be scaled within its wide
-999 to 9999 display count.
The DP460-S strain gage models
are compatible with both bondedfoil type (2 mV/V, 3 mV/V, 4 mV/V)
transducers and higher output,
semiconductor (10 mV/V, 20 mV/V,
30 mV/V) type strain gages.
Its microprocessor design and
ratiometric measuring circuit
assure high accuracy with superior
repeatability. Scaling and calibrating
the DP460-S to display engineering
units from the strain gage input is
similar to the DP460-V models. There
are no pots to drift nor complicated
formulas to compute to set DIP
switch gain ranges. It can achieve
sensitivities as low as 1 µV per count
and can be scaled anywhere within
its wide -999 to 9999 display count.
Meters shown smaller than actual size
The alarm option provides single
(ALM) or dual (ALM2) limit setpoints
that can be set to any point within
the DP460 series’ measuring range.
The user digitally adjusts the setpoint
by pressing two buttons located on
the front panel. Selection of Hi or Lo
(single) alarm or Hi and Lo (dual)
alarms is set by moving a jumper
located on the option card. You can
view the setpoint by pressing the
View button on the front panel. A
light on the front panel illuminates
red for the single alarm or red/yellow
(dual alarm) when the alarm trips.
The DP462 series has the ability
to switch between up to six sensor
inputs of the same type with its
multi-input option. A miniature rotary
switch, accessible from the front
panel, allows convenient switching
between inputs. Sensor hook-up is a
snap-on/off terminal block located at
the rear of the instrument. It is easy
to modify a basic DP460 model and
add the multi-input board (DP460206 or DP460-403) in the field.
The Rack Adaptor Plate permits easy
mounting of DP460 Series indicators
in standard 483 mm (19") instrument
racks. Four versions are available for
mounting 1, 2, 3 or 4 indicators.
