Description
The NI PXIe-2725 is designated by the part number 781986-25 and falls under the category of PXI Switches. This model is a sophisticated 18-Channel 8-bit Programmable Resistor designed to cater to a wide range of applications requiring precise resistance simulation or calibration tasks.
It features 18 channels, each capable of handling a maximum voltage of 60 VDC or 30 VACrms, classified under CAT I for both channel-to-channel and channel-to-ground connections. The device allows a maximum current of 0.3 A per channel and supports a maximum power output of 0.25 W per channel. This resilience ensures reliable performance across all channels simultaneously.
One of the standout features of the PXIe-2725 is its fine resolution of 1 Ω steps, providing users with the ability to perform precise adjustments. The resistance range per channel stretches from 1 Ω to 255 Ω, offering versatility for various testing scenarios. Accuracy is also a key aspect of its design, with an accuracy of less than 5.0% for resistances between 20 Ω to 64 Ω and an improved accuracy of less than 2.0% for resistances ranging from 64 Ω to 255 Ω.
Physically, the PXIe-2725 measures 21.6 cm in length, 2.0 cm in width, and 13.0 cm in height (approximately 8.5 × 0.8 × 5.1 inches), and it weighs around 323 g (11.3 oz). This compact and lightweight design ensures it can be easily integrated into a variety of test systems without occupying excessive space. Connectivity is facilitated through a 37-pin D-SUB connector and 2×2 Micro-Fit connectors, enabling straightforward installation and connection to a host system or other test equipment.
