IO133: Simultaneous Sampling 16-bit Analog I/O Module

Fast simultaneous-sampling, 16-bit analog input and output module with Simulink driver blocks

The IO133 I/O module is a fast, simultaneous-sampling, 16-bit analog input and output module with Simulink® driver blocks. The analog input channels can be sampled simultaneously with a constant conversion time, and the analog output channels can be updated individually or simultaneously.

This I/O module can also be interconnected with other I/O modules to synchronously sample and convert isolated analog input or output channels across the different modules and target machines. Furthermore, 14 individually configurable TTL digital I/O lines are available.

This I/O module is ideal for closed-loop controls and hardware-in-the-loop (HIL) simulations using MATLAB® and Simulink.
