Description
The NI-9403 is a versatile digital I/O module that falls under the C Series Digital I/O category. This module is designed to cater to a range of digital control and monitoring applications, making it a vital component in various setups. It features 32 channels, which can be configured as either input or output, supporting live line-to-line configurations. This flexibility allows users to adapt the module to a wide array of applications.
Moreover, the NI-9403 ensures safety and reliability through its transient isolation feature, which separates the I/O channels from the backplane, minimizing risks associated with electrical interference. Connectivity is facilitated through D-SUB front connectors, ensuring easy and secure connections.
This module is compatible with CompactDAQ and CompactRIO platforms, providing a robust and seamless integration into existing systems. Users can further enhance their setups with compatible accessories such as the NI-9923 Screw Terminal Block, 1 m DSUB Cable, and Din-Rail Spring Terminal Block, which extend the module’s utility and application range.
With an update rate of 7 μs, the NI-9403 offers high-speed data acquisition and control, suitable for demanding applications. It supports various software platforms, including the LabVIEW FPGA Module (for CompactRIO only), LabVIEW Professional Development System for Windows, and LabVIEW Real-Time Module, providing users with flexible programming options.
The module is designed to handle challenging industrial environments, featuring input logic levels of 5 V TTL with Schmitt Trigger Inputs that include hysteresis, offering robust signal processing capabilities. It is also equipped with comprehensive protection mechanisms against overvoltage (±30 V), overcurrent, and short-circuit scenarios, with overcurrent protection setting DIO channels to high impedance for approximately 280 ms.
With a weight of 5.3 oz and an operating temperature range from -40 °C to 70 °C, the NI-9403 is built to perform reliably in a wide range of environmental conditions. Its storage temperature range extends from –
