National Instruments PXIe-2725 PXI Programmable Resistor Module
The PXIe‑2725 (Part Number: 781986-25) is a Programmable Resistor Module that imitates the behavior of resistance-based inputs and outputs such as potentiometers, resistance temperature detectors (RTDs), voltage dividers, and bridge elements. The NI PXIe‑2725 is programmed to control a series of relays to vary the resistance across each channel of an I/O connector. This module comes with software that provides a simple user interface that accepts inputs in units of temperature or resistance, configuring the resistance across each channel.
The PXIe‑2725 is ideal for simulating environmental conditions in hardwareâ€inâ€theâ€loop (HIL) validation. This Programmable Resistor Module uses a 37â€pin Dâ€SUB connector on the front panel, as well as a 2x2 Microâ€Fit connector for easy connection to a PXI Digital Multimeter (DMM). This module has 18 channels with a maximum voltage of 60 VDC, 30 VACrms, CAT I1 (channel-to-channel) and 60 VDC, 30 VACrms, CAT I1 (channel-to-ground). The maximum current is 0.3 A (per channel) and the maximum power is 0.25 W (per channel). This module has resolution in 1 Ω steps; the range is between 1 Ω to 255 Ω (per channel).
For channel set between 20 Ω and 64 Ω, the channel accuracy is <5.0% and <2.0% for channel set between 64 Ω and 255 Ω. The dimensions (L × W × H) of the NI PXIe‑2725 are 21.6 × 2.0 × 13.0 cm (8.5 × 0.8 × 5.1 in.) and the module weighs 323 g (11.3 oz).
