The National Instruments 9422 is an 8-channel, 250 µs sinking/sourcing digital input module. Each channel accommodates 24 V up to 60 V digital input signals and features channel-to-channel isolation for the highest level of safety for automotive and industrial environments. Any discrete level connected to the NI 9422 under 5 V registers as a digital low and any discrete level between 11 and 60 V registers as a digital high. The NI 9422 features 1,390 Vrms transient overvoltage protection between the input channels, 250 Vrms continuous channel-to-channel isolation, and 250 Vrms continuous isolation between each channel and earth ground. The NI 9422 works with a variety of industrial logic levels and signals for direct connection to a wide array of industrial and automotive switches, transducers, and devices.
The NI 9422 module is a correlated digital module, so it can perform correlated operations, triggering, and synchronization when installed in an NI CompactDAQ chassis.
NI recommends the NI 9939 strain-relief connector accessory for use with the NI 9422.
Create a complete system with the NI 9422 and its accessories. However, the NI 9422 is compatible with multiple C Series Platforms, NI CompactDAQ and CompactRIO. Please review the comparison information below and select a platform to begin configuring your system.
Laboratory - 30 g shock and 0.3 grms operational vibration
Field Work - 50 g shock (Class I, Div 2 for Hazardous Locations)
The chassis provides rugged, modular housing for your controller (if using CompactRIO) and C Series modules. A high-performance backplane in the chassis contains the system's data, timing, and triggering buses.
The controller runs your application and interfaces with your C Series modules. If you are using the NI CompactDAQ platform, then a Personal Computer (PC) will act as the controller of your system. However, if the CompactRIO platform is used then an embedded real-time controller will be used instead.
You need software to interface with your hardware and to collect, analyze, present, and store your measurements. This device is compatible with a different programming languages depending on the platform used. If you are using the NI CompactDAQ platform then this device is compatible with LabVIEW, C/C++, Visual Basic, and .NET. However, if the CompactRIO platform is used then this device requires the LabVIEW FPGA Module (sold separately), the LabVIEW Real-Time Module (sold separately) and NI-RIO driver software (included with the hardware).

System Assurance Programs
Reduce your setup time and total cost of ownership, and get a system you can use out of the box with National Instruments system assurance programs. System assurance programs include:
Installation and integration test of all individual hardware
Courtesy installation of system driver sets and application development environments
Extended warranty and calibration coverage for up to five years
Custom documentation plus a custom restore and startup utility
This service is only available for PXI, NI CompactRIO, and NI Compact FieldPoint systems.
National Instruments designs and manufactures all products to minimize failures, however unexpected failures can still occur. Extended warranties provide a fixed economical price at the time of system purchase, covering any repair costs for up to three years. In addition, they offer the following benefits:
Significant cost savings compared to individual repair incidents
Fault location, diagnostics, and repair by NI any time the system product fails
All parts and labor costs covered as well as any adjustments needed to restore the hardware to manufacturing specifications
NI recognizes the need to maintain properly calibrated devices for high-accuracy measurements. NI provides manual calibration procedures, services to recalibrate your products, and automated calibration software to calibrate many NI measurement products.
Return your registered product under warranty at no additional labor and parts cost. NI offers fault location, diagnostics, and repair any time the system fails as well as any adjustments needed to restore the hardware to manufacturing specifications.
