The 65DL1 is a single slot, message-based, VXI instrument Board that provides 16 independent transformer isolated LVDT/RVDT programmable 2-wire outputs (Up to 34 v), with wrap-around self test and an onboard programmable excitation supply. This card is a uniquely versatile instrument because each excitation input and output voltage is programmable. In addition, each channel can be programmed to be controlled by an external DC voltage.
