About the 6527 Device

© National Instruments Corporation
This chapter describes the 6527 devices, lists what you need to get started,
software programming choices, and optional equipment, describes custom
cabling options, and explains how to unpack your board.
Thank you for purchasing a National Instruments 6527 device. Unless
otherwise noted, the text applies to all devices in the 6527 family, which
includes the 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 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 6527 device is a completely jumperless DAQ device for PCI buses
and PXI or CompactPCI chassis and contains 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.
Detailed 6527 device specifications are in Appendix A, Specifications.
