IO135: Simultaneous Sampling 16-bit Analog I/O Module

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

The IO135 I/O module uses high-speed, low-power analog-to-digital converters (ADC) that allow each channel to be sampled simultaneously with a sample rate of 5 microseconds.  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. With fast simultaneous sampling analog inputs and outputs, this I/O module is ideal for closed-loop controls and HIL using MATLAB and Simulink.
