The
Q2000P
is a 3 1/2
digit process
receiver with
extensive zero
and span adjustment
capability
for readout
in engineering
units. The
more popular
process signals
are 4-20 mA,
10-50 mA, 1-5
V and 0-10
V. The Q2000P
can also be
scaled for
other signal
levels. Full-scale
input ranges
are selectable
from ±1
to ±50
mA (current
signal) or
±0.5 to
±20 V
(voltage signal).
Zero is adjustable
up to ±100%
of full-scale
readout for
every input
range.
The Q2000E
is an enhanced
version of
the Q2000P
with an excitation
output for
powering transmitters
and active
transducers.
In many cases,
this output
can eliminate
the need for
a more expensive
external supply.
The output
shares the
ground of the
signal input.
Two output
levels are
jumper-selectable:
10 V dc at
up to 50 mA
and 15 V dc
at up to 25mA.
CONFIGURATION
AND CALIBRATION
The price of
the Q2000P
and Q2000E
includes configura-
tion and calibration,
normally provided
by an authorized
Newport distributor.
Both models
can also be
configured
and scaled
in the field.
Full-scale
signal, coarse-span
and coarse-zero
ranges are
selected by
plug-in jumpers.
A complete
set of internal
shunts and
attenuators
are already
on board. Fine-zero
and fine-span
potentiometers
are accessible
behind the
lens to allow
final calibration
or field recalibration
without removal
of the panel
meter.
POWER AND
DISPLAY OPTIONS
Six types of
meter power
are available:
120 V ac, 240
V ac, 24 V
ac, 5 V dc,
isolated 9-32
V dc and isolated
26-56 V dc.
An LED display
is standard.
An LCD display
is avail- able
and is useful
for viewing
in bright ambient
light.
ANALOG OUTPUT
OPTIONS
A 1 mV/count
(±2 V
full-scale)
analog output
is standard
and is ideal
for driving
a strip-chart
recorder. An
additional
analog output
can be provided
by an optional
vertical plug-in
board. Available
output signals
are 0-5 V dc,
0-10 V dc,
0-1 mA (source
or sink), and
4-20 mA (source
or sink). The
top and bottom
of each output
range can be
scaled to fit
a user-selected
display span.
CONTROL
OUTPUT OPTIONS
Additional
outputs can
be provided
by a horizontal
upper board.
Available options
include single-setpoint
control with
one 10 A relay,
dual-setpoint
control with
two 10 A relays,
4-20 mA proportional
control (source
or sink), time-proportional
2 A solid-state
relay control,
and isolated,
parallel BCD
output. For
additional
information,
please refer
to the QUANTA
and Mechanical
sections.
