VIO1254A.MT

Fast Sensor Measurement Card
Contact Us

The VIO1254A.MT is designed for high‑resolution measurement of dynamic signals from acceleration, pressure and force sensors with a maximum sampling rate of 200 kSa/s.
The card provides four galvanically isolated channels with individual sensor excitation that can be configured independently in three measurement modes.
It supports sensors with IEPE, ratiometric or voltage output.
