QUANTA Models Q2000M and Q2000R are low-cost, 3 1/2 digit indicator/controllers for 100 ohm platinum RTD's with alpha of 0.00385. They are complete with sensor excitation and break detection. Resolution can be 1° (Q2000M) or 0.1° (Q2000R). Readout can be in °C or °F, as selected by plug-in jumpers. What makes QUANTA exceptional is the wide choice of options.

INPUT POWER AND DISPLAY OPTIONS
Six types of meter power are available: 120 Vac, 240 Vac, 24 Vac, 5 Vdc, isolated 9-32 V dc and isolated 26-56 Vdc. An LED display is standard. An LCD display is optional and is recommended 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 Vdc, 0-10 Vdc, 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, Options, and Mechanical sections.
