OPTIONS
Analog output for user-selected span Single-setpoint 10 A relay control Dual-setpoint 10 A relay control Proportional 4-20 mA control Time-proportional 2 A SS relay control Parallel BCD output, isolated NEMA-4 splash-proof lens cover QUANTA Models Q2000J, Q2000K and Q2000T are 3 1/2 digit indicator/controllers for thermocouple types J, K and T, respectively. They are complete with linearization, cold-junction compensation, and sensor-break detection. Readout is in °C or °F with 1° resolution, as selected by push-on jumpers. What makes QUANTA exceptional is the wide choice of options. INPUT 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 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 useful 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, Options, and Mechanical sections.
