Multiplexer Expansion
To handle large channel counts, you can expand the size of the multiplexer with additional NI PXI-2501/2503 modules. NI TB-2605 terminal block has two analog bus connectors to allow connection of two other PXI-2501/2503s. Connecting two NI PXI-2501/2503 modules using their analog bus in 2-wire 24×1 multiplexer topology creates a 2-wire 48×1 multiplexer. Using the LV6-BAN4 cable you can also route the common to an NI 4070 DMM for measurement.
