IO131: Simultaneous-Sampling, 16-bit Analog I/O Module

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

The IO131 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.

The analog inputs offer software selectable ±5 V and ±10 V bipolar input voltage ranges and the sampling rate is up to 200 kSPS.

The analog outputs offer software selectable 0-5 V, 0-10 V, ±5 V and ±10 V output voltage ranges. The conversion time is typically 10 μs, resulting in a maximum update rate of 100 kSPS.

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.

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