The NI 9402 is a 4-channel, 55 ns, LVTTL digital input/output module designed for use with NI CompactDAQ and CompactRIO systems. It provides four bidirectional digital channels that support 3.3 V/5 V logic levels and can be configured for input or output on a per-channel basis. The module features a fast 55 ns response time, making it suitable for high-speed digital applications such as pulse generation, event counting, and digital communication. The NI 9402 connects via a 25-pin D-SUB connector and is engineered for reliable operation in industrial environments. It is compatible with NI LabVIEW and other NI software tools for easy integration and programming.
