The QUANTA Q9000M is a 4-digit indicator/controller with a wide choice of output options. It provides 0.1 degree resolution for 100 ohm platinum RTD's with alpha of 0.00385. It is complete with sensor excitation and break detection. Readout can be in °C or °F, as selected by plug-in jumpers.

POWER OPTIONS
Six types of meter power are available: 120 Vac, 240 Vac, 24 Vac, 5 Vdc, isolated 9-32 Vdc, or isolated 26-56 Vdc.

ANALOG OUTPUT OPTIONS
A 1 mV/degree (±1 V full-scale) analog output is standard and is suitable 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. One advantage in using the Q9000M as a 4-20 mA transmitter is that the current signal tracks the display, and hence is linearized.

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.
