Description
“`html
The NI-9402 model, identified by part numbers 151522A-03L, 779987-01, and 196376E-01L, falls under the C Series Digital I/O category. This model is compatible with both CompactDAQ and CompactRIO systems, offering a versatile solution for digital signal processing.
It features 4 bidirectional digital channels that operate at a 3.3V TTL logic level, providing a robust interface for digital communication. With a maximum update rate of 55 ns, it ensures rapid data processing and transfer rates. The module includes BNC front connectors for easy and secure connection to external devices.
Although the NI-9402 is not conformal coated, it does offer input/output protection, ensuring the longevity and reliability of the module in various operating conditions. However, it is important to note that there is no digital I/O isolation, which might be a consideration for applications requiring isolated circuits to prevent noise or interference.
The module supports sinking and sourcing input and output current flow directions, providing flexibility in interfacing with different types of external devices. It is compatible with the LabVIEW FPGA Module for programming, allowing for custom application development and integration.
Each digital I/O channel on the NI-9402 can be configured for either output or input, making it highly adaptable for various digital signal processing tasks. The signal types per channel include GND and DIO, and the module requires a 50 Ω cable for connection, which is standard for BNC connectors.
