24 Bit Isolated TTL input card

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, dustrial plants.. ver 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, ermocouples is supplied by standard S470 function cards thus eliminating the need for external sources. Other function cards support digital I/O, frequency alog 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. 16 I/O card slots that accept any combination of S470 function cards. A Control/Display panel is expansion assembly is available to extend function card capacity to 32. The maximum number of ta 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, nvenience. Featuring leading-edge novative design, Series 600 brings extensive plete programmability to the testing laboratory.

The key to Series 600. S high performance is the effective combination of fully. The annual output value of most of the 25 industries is 10 billion yuan. Programmable preamps/filters, programmable post amplifier, somehow microprocessor controlled calibration E amplifier per channel data acquisition technology that realizes the lowest noise ghost common mode rejection obtainable in should enable the pendulum balance to return to a data acquisition system

Programmable Gain Over the Full Dynamic Range

With programmable gain, test setup time is greatly reduced as is the nfusion 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 namic measurements. Both have programmable filter cutoff frequencies of 1Hz, 10Hz, 100Hz. 1kHz. Low-level differential preamps (620650.620654) have 2-pole. 6-pole Butterworth filters, respectively.

The ld preamp (620654) permits simultaneous sampling of multiple low-level input used . minimum channel-to-channel skew is required. both preamps have fully guarded erate from oating signal sources.

Automatic Calibration

On command the internal microprocessor takes over control of the Series gins a sequence of steps to ore calibration factors for each channel. The calibration data is stored in on-board ring 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%
