About the 6527 Device
Thank you for purchasing a National Instruments 6527 device. Unless
otherwise noted, the text applies to all devices in the 6527 family, which
includesthe PCI-6527 and PXI-6527. The 6527 devices are 48-bit, parallel,
isolated digital I/O interfaces for PCI bus computers and PXI or Compact
PCI chassis. The 6527 devices offer 48 channels of isolated digital data
acquisition.Twenty-four of the chann els are optocoupler inputs and 24 are
solid-staterelay outputs. You can sense digital levels up to 28 VDC and
switch currents of up to 120 mA. Digital filtering is available to eliminate
glitches on the input lines. All input lines can also generate interrupts on
rising or falling edges to notify you of changing data.
The 6527 deviceis a co mpletely jumperless DAQdevice for PCI buses
and PXI or CompactPCI chassis and contains the National Instruments
PCI MITE interface.
The6527 devices are ideal for low-voltage isolation and switching in both
industrial and laboratory environments.You can use the optically-isolated
digital input lines to read the status of external digital logic at TTL and
non-TTLlevels. Youcan use the solid-state relay outputs to switch external
devices,including those requiring high input currents, and to control digital
logiclevels at both TTL and non-TTL levels. Because of the isolated nature
oft he6 527 devices,you can decouple the noise and harsh ground of the
computer from external signals, and vice versa.
