· The NEFF System 470 (S470) DAS is a complete,
low cost moderate-speed DAS for use in computer-based applications. The S470 is
designed primarily for computer automated data acquisition in test facilities,
laboratories and industrial plants or wherever a moderate-speed DAS is
required.
· The S470 is designed to accept analog inputs
ranging from 5mV to 10.24V full scale in 12 programmable steps. Signal
conditioning for sensors such as strain gages, RTDs, potentiometers and thermocouples
is supplied by standard S470 function cards thus eliminating the need for
external sources. Other function cards support digital I/O, frequency
measurement and analog output.
· S470 consists of a 7-inch high, 19-inch wide
enclosure with power supply, backplane wiring, I/O Control Logic printed
circuit card, Analog Subassembly printed circuit card and 16 I/O card slots
that accept any combination of S470 function cards. A Control/Display panel is
optional and an expansion assembly is available to extend function card
capacity to 32. The maximum number of channels or data points to be serviced
depends on the type of function cards used. Thirty-two 16-channel Multiplexer
cards, for example, provide 512 channels of analog input while a full complement
of 32-bit TTL input cards accommodate 1024 single data points.
· The Series 600 is NEFF's top-of-the-line data
acquisition system providing the utmost in performance, accuracy and
convenience. Featuring leading-edge technology and innovative design, Series
600 brings extensive automation and complete programmability to the testing
laboratory.
· The key to Series 600's high performance is
the effective combination of fully programmable preamp/filters, programmable
post amplifier, sophisticated microprocessor-controlled calibration circuits
and the amplifier-per-channel data acquisition technique that realizes the
lowest noise level and highest common mode rejection obtainable in a data
acquisition system.
· Programmable Gain Over the Full Dynamic Range
With
programmable gain, test setup time is greatly reduced as is the bother and
confusion of manual switch settings. In Series 600 the range of each channel is
programmable from +/-5mV full scale to +/-10.24V full scale in 12 binary steps.
· Preamps Include Programmable Filter
Two types
of input preamps are available in Series 600 to allow both static and dynamic
measurements. Both have programmable filter cutoff frequencies of 1Hz, 10Hz,
100Hz and 1kHz. Low-level differential preamps (620650 and 620654) have 2-pole
and 6-pole Butterworth filters, respectively.
· The sample and hold preamp (620654) permits
simultaneous sampling of multiple low-level input channels and is used where
minimum channel-to-channel skew is required. both preamps have fully guarded
inputs and operate from grounded or floating signal sources.
· Automatic Calibration
On command
the internal microprocessor takes over control of the Series 600 and begins a
sequence of steps to derive and store calibration factors for each channel. The
calibration data is stored in on-board memories and during run mode are summed
with the post amplifier output voltage to obtain fully calibrated signals for
conversion by the ADC.
· The automatic calibration procedure results
in static accuracy of (0.02%
