The National Instruments 9221 is a C Series module for high-speed measurements with a range of ±60 V. This wider voltage range makes this module well suited for industrial-level, automotive, or even smaller-cell battery measurements.
As with the majority of C Series modules, the NI 9221 is protected from harmful voltage spikes of up to 2,300 Vrms. This means that no harmful voltage within the isolation rating can harm other modules in the system, the chassis, or any connected computer equipment. In addition to the absolute protection from the isolation, there is up to 100 V of overvoltage protection for errant signal connection or unexpected outputs to the channels.
There are two connector options for the NI 9221 - a 10-position screw-terminal connector for direct connectivity and a 25-position D-Sub connector. The industry-standard 25-position D-Sub connector provides for low-cost cabling to a wide variety of accessories available from NI or other vendors. Some vendors also offer custom D-Sub cable fabrication services and provide cables with a pinout that matches your exact application needs.
NI recommends the NI 9932 strain-relief connector accessory for the National Instruments cRIO-9221 analog input module. The NI 9934 (or other 25-pin D-Sub connector) is required to use the NI 9221 with a D-Sub module. The NI 9934 includes a screw-terminal connector with strain relief as well as a D-Sub solder cup backshell for creating custom cable assemblies.
For a 24-bit, ±60 V C Series module with channel-to-channel isolation, consider the NI 9229.
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.
