The NI 9401 is an 8-channel, 100 ns bidirectional digital input module for any NI CompactDAQ or CompactRIO chassis. You can configure the direction of the digital lines on the NI 9401 for input or output by nibble (4 bits). Thus, you can program the NI 9401 for three configurations: eight digital inputs, eight digital outputs, or four digital inputs and four digital outputs. With reconfigurable I/O (RIO) technology (CompactRIO only), you can use the LabVIEW FPGA Module to program the NI 9401 for implementing custom, high-speed counter/timers; digital communication protocols; pulse generation; and much more. Each channel is compatible with 5 V/TTL signals and features 1,000 Vrms transient isolation between the I/O channels and the backplane.

Recommended Accessories
-The NI 9924 (or other 25-pin D-SUB connector)

EMC Performance
To ensure EMC compliance, you must use a ferrite bead, such as NI part number 782803-01.
