INSTRUMENTATION

The DP2000/9000A and DP2000/9000B are a
high-quality ±1999 or ±9999 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 current­loop signals to a central control room and provide local
alarm or control. A
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.

actual size.

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.
