The NI 9381 multifunction I/O module for NI CompactRIO was designed to be a single, cost-effective module for general-purpose system I/O. By combining common I/O circuitry into a single module, the NI 9381 helps system designers fit more functionality into a single system.

Analog I/O Timing
The analog circuitry on the NI 9381 is a multiplexed architecture that shares a single timing engine that can sample up to 20 kS/s. This means the sample rate is a function of up to 20 kS/s divided by the number of both analog input and output channels used. The module features an overall update rate of 1,250 S/s when using all eight analog input and all eight analog output channels together.
