# NI-9401 National Instruments Module Used

**Features:**

-   5 V/TTL
-   8 Bidirectional Channels
-   100 ns
-   C Series Digital Module

The NI-9401 is a configurable digital I/O interface for input or output in 4-bit increments. Therefore, the NI-9401 can create three configurations: 8 digital inputs, 8 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 more. Each channel features transient isolation between the I/O channels and the backplane.
