VXI 16-Channel, 2-Wire LVDT/RVDT Simulation

NAI’s 65DL1 is a 16-channel, 2-wire, LVDT/RVDT Simulation Instrument on a VXI board. This single-slot, message-based board provides 16 independent, transformer-isolated, LVDT/RVDT, programmable 2-wire outputs (up to 34 V), wrap-around self-test, and an onboard programmable excitation supply.

The board is a uniquely versatile instrument as each excitation input and output voltage is programmable. In addition, each channel can be programmed to be controlled by an external DC voltage. The 65DL1 is ideally suited for defense, commercial aerospace, and industrial applications.

This product is Mature. For existing customers only; not recommended for new applications. Please refer to our Products page for a listing of current products.
