Description
The National Instruments PXI-2722 Programmable Resistor Module is identified by its part number 781985-22 and falls under the category of PXI Switches. This module is specifically designed for simulating environmental conditions in Hardware-In-the-Loop (HIL) validation applications. It features 5 channels with a 16-Bit resolution, allowing for precise control and simulation of various conditions.
The PXI-2722 can handle a maximum voltage of 60 VDC and 30 VACrms, CAT I, both channel-to-channel and channel-to-ground, ensuring safe operation across a range of experimental setups. Each channel of the PXI-2722 can carry a maximum current of 0.3 A and deliver a maximum power of 0.25 W, suitable for a variety of simulation needs. The module boasts a Temperature Coefficient of Resistance (TCR) of 100 ppm, ensuring stability and accuracy in resistance simulation over a range of temperatures.
With a steps resolution of 0.25 Ω, the PXI-2722 offers precise control over resistance values, making it ideal for simulating various environmental conditions. The resistance range per channel is from 0.25 Ω to 16,320 Ω, providing a wide spectrum for simulation purposes. The typical channel accuracy is <10.0% for resistances between 20 Ω to 40 Ω, and <5.0% for resistances between 40 Ω to 120 Ω, highlighting the module’s reliability and precision.
Furthermore, the PXI-2722 can simultaneously drive up to 89 relays, showcasing its capability to handle multiple channels concurrently, which is crucial for complex and comprehensive HIL testing scenarios. This makes the PXI-2722 an essential tool for engineers and researchers aiming to simulate and test under highly variable and controlled resistance conditions.
