- Legacy digital I/O devices for ISA, PCI, and PXI
- 5 V TTL, 2.5 mA current drive digital I/O for ISA, PCI, and PXI
- 28 V inputs, 60 V outputs digital I/O for PCI and PXI
- NI recommends the NI 6509, NI 651x, or NI 6528 devices with NI-DAQmx technology for new applications
For new applications, consider using the new NI-DAQmx-enabled digital I/O devices. NI 6509 devices offer the industrial feature set in addition to 24 mA current drive at a lower cost than the NI PCI-DIO-96/NI 6508 devices. Instead of the NI 6527, consider using the NI 651x devices with bank optical isolation and industrial feature set available at a lower cost. For channel-channel isolation consider using the NI 6528 devices which offer higher current drive and the industrial feature set at the same price of the NI 6527.
