The AR-200/AR-400 series is a range of high-performance dynamic signal
acquisition modules that are designed specifically for vibration monitoring
and analysis. The maximum simultaneous sampling rate for each channel on the
AR-200 and AR-400 is up to 200k-Hz and 125k-Hz respectively. The modules
include a built-in 3mA excitation current to power the Integrated Electronics
Piezo-Electric (IEPE) accelerometers and a 16-bit A/D converter.
