The S470 is designed primarily for computer automated data acquisition in test facilities, laboratories.industrial 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, potentiometers.thermocouples is supplied by standard S470 function cards thus eliminating the need for external sources. Other function cards support digital I/O, frequency measurement.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.16 I/O card slots that accept any combination of S470 function cards. A Control/Display panel is optional.an expansion assembly is available to extend function card capacity to 32. The maximum number of channels.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.convenience. Featuring leading-edge technology.innovative design, Series 600 brings extensive automation.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.the amplifier-per-channel data acquisition technique that realizes the lowest noise level.highest common mode rejection obtainable in a data acquisition system.• Programmable Gain Over the Full Dynamic RangeWith programmable gain, test setup time is greatly reduced as is the bother.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 FilterTwo types of input preamps are available in Series 600 to allow both static.dynamic measurements.
