Vanciet's PCI/CPCI/PXI-4104 series LVDT/RVDT simulation card is a series of 32-bit PCI/CPCI/PXI bus specification simulation test equipment. The board supports 16 bit resolution and 8-channel (2-lines, 3-lines and 4-lines) output simulation function.

The board can receive excitation signal input of a wide range of frequencies (40Hz~10kHz), and can adapt to excitation signal input of 1V~7V AC RMS. The simulation output of 3-lines, 4-lines or 2-lines system can be realized according to the needs of users. Each group of signals includes two voltage outputs of high-end and low-end. The simulation signal of LVDT sensor with peak value less than 20V can be programmable.
