Description
The part number 142907A-01L refers to a C Series Digital I/O module, specifically model NI-9475. This module is designed to provide 8 digital output channels, with each channel capable of handling a maximum current of 1 A and a maximum voltage of 60 VDC. The connections to the module are made using a 25-pin DSUB connector, ensuring a secure and reliable connection for your digital signals.
One of the key features of the NI-9475 is its channel-to-earth ground isolation, also rated at 60 VDC. This feature enhances the safety and reliability of the module by preventing potential ground loops and protecting the device from unexpected ground potential rises.
The NI-9475 is compatible with both CompactRIO and CompactDAQ systems, making it a versatile choice for a wide range of applications. Additionally, this module supports hot-swapping, meaning it can be replaced or removed without needing to power down the entire system, significantly reducing downtime.
Another notable capability of the NI-9475 is its sourcing outputs, which allow it to supply power to external devices, and it boasts an impressive maximum update rate of 1 us. This high update rate enables the module to respond quickly to changes in control signals, making it ideal for high-speed applications.
The module is available in two part numbers: 780132-01 for the standard version and 780132-02 for the conformal coated version, which offers additional protection against harsh environmental conditions. The output impedance of the module is a low 0.14 Ω, and it is capable of maintaining an output voltage up to 0.14 Ω. Furthermore, it features a short-circuit trip time of 10 µs at 13 A, providing robust protection against short circuits.
