Introduction
The PCI-6308 series products are isolated analog output cards. The
PCI-6308 series includes three cards:
•PCI-6308V: Isolated 8-CH voltage output card
•PCI-6308A: Isolated 8-CH voltage and current output card
•PCI-6304V: Isolated 4-CH voltage output card
The PCI-6308V is high-performance, 12-bit analog output boards with
PCI interface. The PCI-6308V provide 8-CH identical voltage output
channels, each of channel has: (1) bipolar ±10V voltage outputs; (2)
unipolar 0~+10V voltage output; and (3) unipolar 0 to user defined
voltage output. The DA chip is the DAC-4814AP that is a state-of-the-
art, fully monotonic, digital to analog converter. This device employs
ultra-stable nichrome (NiCr) thin-film resistors to provide monotonicity,
low distortion, and low differential linearity error over long period of
time.
The PCI-6304V is for large quantity OEM only. It is fully compatible
with PCI-6308V, but with four voltage-output channels only.
functionality, software interface and detail operation of PCI-6304V is
exactly the same as PCI-6308V. Therefore, there will have no more
description about PCI-6304V in this manual.
The PCI-6308A is the combination of PCI-6308V with an 8-CH current
output extended board called EXP-8A. The EXP-8A board includes 8
precision voltage-to-current converters/transmitters, which convert
voltage output of PCI-6308V to current source output. The EXP-8A is
piggy back on the PCI-6308V. Therefore, the PCI-6308A provides not
only voltage output but also current output. The total number of analog
output channel is still 8.
