Networked Data Acquisition Unit
Information
The 2640A and 2645A NetDAQ® Networked Data Acquisition Units
are 20-channel front ends that operate in conjunction with
NetDAQ Logger for Windows (hereafter known as NetDAQ Logger)
to form a data acquisition system.
The instruments measure dc volts, ac volts, Ohms,
temperature, frequency, and dc current. Temperature
measurements use thermocouples or resistance-temperature
detectors (RTDs). To measure other parameters, use an
appropriate transducer. The instrument also includes ten
computed channels for custom calculations based on measured
values.
The NetDAQ instruments scan the 20 analog channels in
sequence and calculate the values for the ten computed
channels. Interval timers, alarm conditions, and/or an
external signal input can trigger scans. The NetDAQ Logger
Software configures and controls up to 20 instruments via an
Ethernet connection. The Software provides the means to view
scan data and log it into files.
The 2640A and 2645A instruments (Figure 1-1) are identical
in operation and appearance, and vary only in emphasis. The
2640A emphasizes precision and supports up to 100
measurements per second, with 5 digits of resolution, .02%
accuracy, and 150-volt common mode voltage (300 volts on
channels 1 and 11). The 2645A emphasizes increased
measurement speed supporting up to 1000 measurements per
second, with 4 digits of resolution, 0.04% accuracy, and 50-
volt common mode voltage.
