Fast 16-bit analog module with 16/8 multiplexed analog input channels and 8 analog output channels

This I/O module is similar to the IO102. It offers the same sampling/conversion times for the analog inputs respectively same update/settling times for the analog outputs as the IO102. It offers 16/8 input channels and 8 analog output channels. Digital I/O is not available on this module.

Each IO103 I/O module comes with xPC Target driver blocks and Simulink test models, an external shielded 50-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.
