Speedgoat offers a range of digital I/O modules, differentiated by the number of available channels, type of signal levels, isolation, and voltage/current levels.

All I/O modules come with Simulink driver blocks for seamless Simulink workflow.

If you can't find a fixed-functionality digital I/O module with the characteristics you're looking for, do also have a look at our Simulink programmable FPGAs which allow Speedgoat to rapidly implement custom digital I/O connectivity.

Pulse train support such as for encoders and PWM is also available.
