Qxxxx-A/Qxxxx-B
The QUANTA Q2000A and Q2000B are a high-quality ±1,999-count DC voltmeter and ammeter, respectively. The base meters are digital indicators for use in electrically-noisy industrial environments. With the addition of analog and control outputs, these meters can provide two-wire current-loop signals to a central control room and provide local alarm or control. A 1/8 DIN case with screw terminals for signal and power is standard. A wide range of options are available.
POWER AND DISPLAY OPTIONS
The QUANTA Q2000A and Q2000B are 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 and 9-32 V dc (isolated) and 26-56 V dc (isolated).
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.
