Description
The NI-9401 is a versatile module designed for C Series digital input/output tasks. It features 8 channels that are capable of functioning as either digital inputs, digital outputs, or a combination of both, providing flexibility for various applications. The module is uniquely identifiable by its part numbers 779351-01 and 782401-01, with the latter designated as the conformal coated version for added protection in harsh environments.
With a rapid maximum I/O propagation delay of just 100 ns, the NI-9401 ensures timely response and processing of signals. This performance is complemented by the module’s compatibility with 5 V/TTL signal levels, making it suitable for a wide range of digital devices. Bidirectional channels add to the module’s versatility, allowing each channel to be configured according to the specific needs of the application.
The module boasts transient isolation between I/O channels and the backplane, enhancing reliability and protecting against electrical noise and transient voltage spikes. This feature is particularly important in industrial settings where electrical interference is common.
Integration with LabVIEW FPGA Module is seamless thanks to the module’s support for Reconfigurable I/O (RIO) technology, although this capability is limited to CompactRIO systems. This integration allows users to develop custom firmware that can be loaded onto the module, offering unparalleled flexibility in how the module’s I/O is managed and controlled.
The physical connection to the module is made through a D-SUB front connector, ensuring a secure and reliable link to external devices. Weighing in at just 5.1 oz and capable of operating across a wide temperature range from -40 °C to 70 °C, the NI-9401 is both lightweight and robust, suitable for demanding applications and environments.
In summary, the NI-9401 offers a high-performance solution for digital input/output tasks with its rapid response time, flexible channel configuration, robust isolation features, and compatibility with advanced programming environments, making it an ideal choice for engineers and developers working on a variety of projects.
