Description
The NI PXIe-2725 is a highly versatile and programmable resistor designed for PXI systems, with a part number 781986-25. This unit falls under the category of PXI Switches, specifically designed to meet the needs of complex electronic test systems. It features an 18-Channel 8-bit Programmable Resistor, providing users with a wide range of resistance adjustments for various testing scenarios.
The PXIe-2725 comes equipped with a 37-pin D-SUB and 2×2 Micro-Fit connectors, ensuring easy integration into existing PXI configurations. It boasts 18 channels, each capable of handling a maximum voltage of 60 VDC, 30 VACrms, CAT I1 (channel-to-channel and channel-to-ground), with a maximum current of 0.3 A per channel. This makes it suitable for a broad range of test and measurement tasks.
Each channel on the PXIe-2725 can dissipate up to 0.25 W of power, and offers a fine resolution of 1 Ω steps within a resistance range of 1 Ω to 255 Ω. This level of precision allows for accurate simulation of resistive loads or sensor signals in a controlled environment. The device’s accuracy varies across the resistance range, with an accuracy of <5.0% for resistances between 20 Ω and 64 Ω, and an improved accuracy of <2.0% for resistances between 64 Ω and 255 Ω.
Physically, the PXIe-2725 measures 21.6 × 2.0 × 13.0 cm (8.5 × 0.8 × 5.1 in.) and weighs approximately 323 g (11.3 oz). Its compact size and lightweight design make it an ideal choice for high-density PX
