Introduction

PCI-1747U is a high-resolution high channel count analog input card for the PCI bus. Its sampling rate is up to 250 kS/s and 16-bit resolution provides the power needed for most

data acquisition applications. PCI-1747U provides 64 single-ended, 32 differential analog input channels or a combination of these. It also has built in a 1k-sample FIFO buffer for

analog input data.

 16-bit high resolution

 250 kS/s sampling rate

 64 S.E. or 32 Diff. AI, or a combination

 Auto calibration function

 Unipolar/Bipolar input range

 1k samples FIFO for AI

 Bus master DMA data transfer

 Universal PCI Bus

 BoardID™ switch

250 kS/s, 16-bit, 64-ch Analog Input Card

 Resolution 16-bit

 Base Clock Channel 1: 10 MHz

Channel 2: Takes input from output of channel 1
