Q2000-AVR4
Meter shown smaller
than actual size.
The Q2/9000A and Q2/9000B are a high-quality
±1,999 or ±9,999 count DC voltmeter and ammeter,
respectively. The base meters are digital indicators for
use in electrically-noisy industrial environments. With
the addition of analog and control outputs, these meters
can provide two-wire current-loop signals to a central
control room and provide local alarm or control. A ¹â„8
DIN case with screw terminals for signal and power is
standard. A wide range of options are available.
Power and Display Options
Six types of power supplies are available: 120 Vac,
240 Vac, 24 Vac, 5 Vdc, isolated 9 to 32 Vdc and
isolated 26 to 56 Vdc. An LED display is standard,
an LCD display is optional and is recommended for
viewing in bright ambient light. A NEMA 4 (IP65)
splash-proof lens cover is available.
Signal input and power connections are made via a
rear barrier terminal strip. The motherboard rear edge
connector provides access to hold and test, polarity,
clock, and the standard analog output and optional
analog outputs. Decimal point positions can be selected
by jumpers.
Analog Output Options
A 1 mV/count (±2V full-scale) or 0.1 mV/count
(±1V fullscale) 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 to 5 Vdc,
0 to 10 Vdc, 0 to 1 mA (source or sink) and 4 to 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 to 20 mA proportional control
(source or sink), time-proportional 2 A solid-state
relay control, and isolated, parallel BCD output.
