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 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.Furthermore, 14 individually configurable TTL digital I/O lines are available, which can generate interrupts triggered on the rising or falling edge, or both.

With it's fast simultaneous sampling analog inputs and outputs, this I/O module is ideal for closed-loop controls and HIL using MATLAB® and Simulink.
