·         The NEFF System 470 (S470) DAS is a complete,low cost moderate-speed DAS for use.computer-based applications. The S470 isdesigned primarily for computer automated data acquisition.test facilities,laboratories.industrial plants.wherever a moderate-speed DAS isrequired.

·         The S470 is designed to accept analog inputsranging from 5mV to 10.24V full scale.12 programmable steps. Signalconditioning for sensors such as strain gages, RTDs, potentiometers andthermocouples is supplied by standard S470 function cards thus eliminating theneed for external sources. Other function cards support digital I/O, frequencymeasurement.analog output.

·         S470 consists of a 7-inch high, 19-inch wideenclosure with power supply, backplane wiring, I/O Control Logic printedcircuit card, Analog Subassembly printed circuit card.16 I/O card slotsthat accept any combination of S470 function cards. A Control/Display panel isoptional.an expansion assembly is available to extend function cardcapacity to 32.
