NI 9401

The National Instruments 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 LabVIEW FPGA 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.

The NI 9934 (or other 25-pin D-Sub connector) is required for use with the NI 9401 module. The module includes a screw-terminal connector with strain relief as well as a D-Sub solder cup backshell for creating custom cable assemblies.
