LVDT / RVDT Simulation, 2 & 3 Channel


See D/L, D/R for newest technology.

NAI offers two types of programmable, isolated output, LVDT/RVDT simulation (DL(R)V) function modules.

The first module type is a two-channel, when programmed for three-wire format, and four-channel when programmed for two-wire format respectively. Both have high-power (1.2 VA max.) output drive capability (supported on certain platforms).

The second is a higher density three-channel (programmable for two, three or four-wire formats) form factor module supported on all multi-function I/O platforms with standard-power (0.1 VA max.) output drive capability.

All DL(R)V modules feature a wrap-around self-test capability and most platforms support an optional programmable AC excitation supply. Utilizing state-of-the-art technologies and design algorithms, many useful application features such as excitation voltage and frequency measurement, excitation loss detection and many others are “built-in.” They can be programmed (and re-programmed) in the field for any excitation and simulating signal voltage between 2 and 28 V full scale range. Operating frequency between 47 Hz and 10 KHz can be specified (see part number). Individual excitation inputs are supplied for each A and B output pair.
