The DP2000/9000-O is a panel mount resistance meter
with direct readout in ohms. Resistance ranges are
jumper selectable. It is complete with current excitation
and open resistance detection. With the addition of
analog and control outputs, it can be incorporated as
a system component in ATE and closed-loop control
applications.
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 (IP65) 4 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 (±2 V full-scale) or 0.1 mV/count (±1 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 plugin 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.
