National Instruments 778836-01  8-channel, bidirectional digital I/O module

The National Instruments 778836-01, identified as the NI 9401 C Series Bidirectional Digital I/O Module, is a versatile industrial control device designed for general-purpose digital input and output applications. This module integrates seamlessly with CompactDAQ or CompactRIO systems, offering a flexible solution for industries requiring reliable digital signal handling, such as manufacturing, automation, and embedded systems. 

The NI 9401 is an 8-channel, bidirectional digital I/O module optimized for interfacing with digital sensors, actuators, and control systems. It supports both input and output operations on each channel, allowing dynamic reconfiguration during runtime. Key features include:

Bidirectional Channels: Each channel can independently switch between input and output modes via software.

High-Speed Operation: Supports rates up to 1 MHz for digital pulse generation and counting.

Industrial Compatibility: 24 V logic levels and robust connector design for reliable operation in noisy environments.

Channel-to-Channel Isolation: 500 Vrms isolation protects against ground loops and electrical noise.

Software Integration: Works with NI-DAQmx driver for easy configuration and control via LabVIEW, LabWindows/CVI, and third-party tools like Python and MATLAB.
