Configurable I/O module

The IO323 is a versatile configurable I/O module combining accurate analog and digital input and output channels with a large selection of standard interfaces such as PWM, SPI, and I2C. The module is ideal for control applications in various fields, for example, the automotive and power electronics industries.

You can expand the IO323 capabilities with rear plug-ins for additional digital lines or resolver measurement functionalities.
Furthermore, Speedgoat’s configurable workflow is ideal for applic-ations with closed-loop sample rates less than 20 kHz.
