Overview SLSC Cards
SET-1240 xVDT card

SET 1240 – xVDT Emulator Card

The SET-1240 xVDT card can emulate 4/5/6-wire LVDTs, RVDTs and resolvers.
The card offers 8 independent, galvanically isolated channels. In addition to a wide excitation frequency range from 400Hz to 10kHz, the card also offers various self-test options. The transformers are located on an exchangeable sub-card and can therefore be easily exchanged or specified on request.
