DISPLAY AND POWER OPTIONS
The QUANTA Model Q9000O is available with an LED or an LCD display and with six types of meter power: 120 V ac, 240 V ac, 24 V ac, 5 V dc, 9-32 V dc (isolated) and 26-56 V dc (isolated).

ANALOG OUTPUT OPTIONS
A 0.1 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. The 10A relay options are ideal for ATE and material testing applications, which require ON/OFF control. The BCD output can communicate with programmable controllers and Newport's Model 872A thumbwheel controller. For additional information, please refer to the QUANTA and Mechanical sections.
