Functional Description¡@
The PISO-DA2 is a PCI bus analog output board
with two output channels and isolated 12-bit resolution for IBM personal
computer and compatibility. The output range can be configured as
voltage output by one of the different ranges: ¡Ó10V, ¡Ó5V, 0~10V, 0~5V
or current output using loop sink by the range: 0~20mA or 4~20mA.
Besides, output channel is isolated each other and its isolation range
is increased the voltage more than 3000Vdc. The
output terminals of the PISO-DA2 are two sets of 9-pin D-type female
connectors. PISO-DA2 can be installed in a 5V PCI slot and truly
supports ¡§Plug & Play¡¨ function of PCI-bus. The maximum
conversion rate of the analog output is 10KS/s. It can be
thought as the most cost-effective isolated D/A board
for the PCI bus interface.
