The NI PXI-2722 is a 5-channel, 16-bit programmable resistor module capable of outputting resistance values up to 16 kiloohm in 0.25 ohm steps. Programmable resistors are test modules that replicate the behavior of resistance-based inputs and outputs such as potentiometers, resistance temperature detectors (RTDs), voltage dividers, and bridge elements. The NI 272x programmable resistor modules programmatically control a series of relays to vary the resistance across each channel on the I/O connector. This function is well suited for simulating environmental conditions in hardware-in-the-loop (HIL) validation.

Connectivity
Each NI 272x module uses a 37-pin D-SUB connector and 2x2 Micro-Fit connector on the front panel. National Instruments offers cables and screw terminal blocks for the 37-pin D-SUB connector and a cable accessory to connect the 2x2 Micro-Fit connector to a digital multimeter (DMM).

Software
The NI-272x installer includes reference VIs and example programs for using the device as an RTD, programmable potentiometer, or resistive load. The software provides a simple user interface that accepts inputs in units of temperature or resistance, and configures the resistance across each channel.

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:
