More info

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 litches 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.
