Description
The NI-9402 is a C Series Digital I/O module characterized by its part numbers 779987-01 and 196376E-01L. This module provides 4 Bidirectional Digital Channels, supporting 3.3V TTL digital I/O logic levels for versatile digital signal management. With a maximum update rate of 55 ns, it ensures high-speed performance for demanding applications.
It features BNC front connectors for easy and secure physical connection, utilizing a 50 Ω BNC cable for signal connection. Despite its advanced capabilities, the NI-9402 is not conformal coated, indicating that it does not have an additional protective layer against environmental factors. However, it is designed with I/O protection on each channel, enhancing its durability and reliability in various operational contexts.
One notable feature is its lack of digital I/O isolation, which might influence its application depending on system requirements. It is compatible with CompactDAQ and CompactRIO systems, offering a broad range of deployment options. The input and output types supported by the NI-9402 include Sinking Input, Sinking Output, Sourcing Input, and Sourcing Output, providing flexibility in interfacing with different signal types such as GND and DIO.
Programming the NI-9402 is facilitated through the LabVIEW FPGA Module, specifically for use with CompactRIO systems, enabling users to configure the module software per channel according to their specific application needs. This level of customization ensures that the NI-9402 can meet a wide range of digital I/O requirements, making it a versatile choice for engineers and developers working with digital signaling in CompactDAQ and CompactRIO systems.
