Using the Module
This chapter describes how to connect LVDT, RVDT, resolver, and synchro signals to the
PXIe-4340. It also provides the I/O connector signal pin assignments of the module.
Driver support for the PXIe-4340 was first available in NI-DAQmx 15.5. For the list of devices
supported by a specific release, refer to the
NI-DAQmx Readme
, available on the
version-specific download page or installation media.
Caution
To ensure the specified EMC performance, operate this product only with
shielded cables and shielded accessories. Use only twisted, shielded pair cables for
channel connections.
Caution
To ensure the specified EMC performance, the length of all I/O cables
must be no longer than 30 m (100 ft.).
LVDTs, RVDTs, Resolvers, and Synchros
An LVDT is a device for measuring linear position. Figure 2-1 shows a cut-away view of an
LVDT.
