Key product information and technical features.
The PXI-2720 uses relay-controlled resistor banks to present programmable resistance at its I/O connector. Adjacent banks can be connected internally to form resistor chains, potentiometers, or voltage dividers.
NI-272x Reference VIs provide LabVIEW utility functions that translate requested resistance or temperature values into relay operations. NI-SWITCH 2023 Q1 explicitly lists the PXI-2720 as supported hardware; check the relevant release documentation when selecting a software environment.
