The NI 9203 is a C Series data acquisition module includes eight analog current input channels for high-performance control and monitoring applications. The NI 9203 features programmable input ranges of ±20 mA or 0 to 20 mA, 16-bit resolution, and a 200 kS/s maximum sampling rate. To protect against signal transients, the NI 9203 includes a channel-to-earth ground double isolation barrier (250 Vrms isolation) for safety and noise immunity.

The NI 9203 module ships with screw terminals for signal wire connection. Extra screw terminal connections can be purchased as replacements or spares. In addition, for strain relief, high vibration applications, and high voltage safety, a plastic backshell is available to sercure and protect the signal wire connections. The backshell kit, the NI 9932, is sold separately.

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.

Extended Warranties

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

For more information about your warranty options:


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.


NI training is the fastest, most certain route to productivity with NI tools and successful application development.

Repair Services

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.
