The NI 9403 C Series Digital Module is a versatile and robust digital module that features part numbers 779787-01, 780179-01, and 199027C-03L. This module provides 32 Channel Digital I/O capabilities, making it suitable for a wide range of applications. Each channel can be configured for both input and output with live line-to-line capability, offering flexibility in connecting and controlling various digital devices.
One of the key features of the NI 9403 is its transient isolation between I/O channels and the backplane, ensuring reliable and secure operation even in electrically noisy environments. The module utilizes D-SUB front connectors for easy and convenient connectivity.
The update rate of the NI 9403 is impressively fast at 7 μs, allowing for high-speed data acquisition and control. It is compatible with CompactDAQ and CompactRIO platforms, providing a seamless integration experience. Additionally, it supports various accessories such as the NI-9923 Screw Terminal Block, 1 m DSUB cable, and Din-Rail Spring Terminal Block, further enhancing its versatility.
Software compatibility includes the LabVIEW FPGA Module, LabVIEW professional development system for windows, and the LabVIEW Real-Time module. These software tools provide a powerful and intuitive development environment for creating complex applications.
The module operates at a 5 V TTL logic level and features input characteristics like Schmitt trigger and hysteresis for reliable signal processing. It is designed with overvoltage, overcurrent, and short-circuit protection to safeguard the module and connected equipment. In the event of an overcurrent condition, the module’s DIO channels are set to high impedance for approximately 280 ms as a protective response.
