Connecting LVDT and RVDT Signals
This section provides information regarding connecting LVDT and RVDT signals. Figures 2-3
through 2-5 show the connections made to a 4-, 5-, and 6-wire LVDT or RVDT using the
PXIe-4340 with the TB-4340 terminal block.

Note
The PXIe-4340 does not require connection to the center tap of 5- and 6-wire
LVDTs. For 5-wire sensors, NI recommends leaving your CT lead disconnected. For
6-wire sensors, NI recommends connecting the two CT leads only to each other. For
wire management, you may choose to connect your CT leads to the floating CT
terminal on the TB-4340.
