• The NEFF Systdiv 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 measurdivent 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 Subassdivbly 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 assdivbly 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 compldivent of 32-bit TTL input cards accommodate 1
