【英文介绍】
National Instruments PXI-2722 Programmable resistance module
The National Instruments PXI-2722 (Part number: 781985-22) is a 5-channel, 16-bit PXI programmable resistance module. It is a test module for replicating the performance of resistor-based input/output, including voltage dividers, resistance temperature detectors (RTDS), bridge elements, and potentiometers. The module can be programmed to control the relay array to achieve regulation of each channel of the input/output connector.
This trend makes the NI PXI-2722 an ideal solution for accurately simulating environmental conditions in HIL (hardware-in-the-loop) verification. NI PXI-2722 provides 60 VDC, 30 VACrms, CAT I (channel to channel) and 60 VDC, 30 VACrms, CAT I (channel to ground) maximum voltage, 0.3 A maximum current (per channel), 0.25 W maximum power (per channel), 100 ppm TCR, 0.25Ω step resolution and 0.25Ω to 16,320Ω (per channel) range. When the channel is set to operate between 20 Ω and 40 Ω, the typical channel accuracy remains around <10.0%, and when the channel is set between 40 Ω and 120 Ω, the typical channel accuracy remains around <5.0%.
With this programmable resistor module, users can achieve a simultaneous drive limit of 89 relays. Typical relay life for relays in PXI-2722 programmable resistance modules is 1 × 10 8 cycles (at low power load <50 mW) and 1 × 106 cycles (at full power load <250 mW). The NI PXI-2722 is equipped with a 37-pin D-SUB front panel connector and 2 x 2 Micro-Fit digital multipurpose device port connectors. By design, the module is a 3 U, single-slot, PXI module that consumes 11 W of power at 5 V operation.
