About the 6527 Device
Thank you for purchasing a National Instruments 6527 device. 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
channels are optocoupler inputs and 24 are solid-state relay 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 PCI-6527 and PXI-6527 devices are completely jumperless DAQ
devices for PCI buses and PXI or CompactPCI chassis, respectively. All
devices in this family contain the National Instruments PCI MITE
interface.

The 6527 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-TTL levels. You can use the solid-state relay outputs to switch external
devices, including those requiring high input currents, and to control digital
logic levels at both TTL and non-TTL levels. Because of the isolated nature
of the 6527 devices, you can decouple the noise and harsh ground of the
computer from external signals, and vice versa.
