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 configuration 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.
