Very fast 16-bit analog module with 8 simultaneous-sampling analog input channels and 4 analog output channels

This I/O module is a high-end analog module with a input and output resolution of 16-bit. Because each analog input channel has its own dedicated A/D converter signals are sampled truly simultaneous and the conversion of up to all 8 analog input channels is constant (500ns). Also, each of the 4 analog output channels is equipped with a dedicated D/A converter having a conversion and settling time of 2µs. The I/O module can also be interconnected by trigger lines with additional IO104 to synchronously sample and convert analog input or output channels among the different modules.

Select this very low analog I/O latency module if your application requires high sample rates and to acquire analog signals simultaneously.

Each IO104 I/O module comes with xPC Target driver blocks and Simulink test models, an external shielded 80-pin I/O cable and a terminal board for easy access of all physical I/O signals, and comprehensive documentation.

This I/O module in the PMC form factor and can be used in any Speedgoat real-time target machine with the exception of the Classic real-time target machine.
