The X-NUCLEO-OUT09A1 industrial digital output expansion board for STM32Nucleo provides a powerful and flexible environment for the evaluation of the driving and diagnostic capabilities of the IPS8160HQ octal high-side smart power solid state relay, in a digital output module connected to 0.7 A industrial loads. The X-NUCLEO-OUT09A1 interfaces with the microcontroller on the STM32 Nucleo via 5 kV optocouplers driven by GPIO pins and Arduino R3 connectors. The expansion board can be connected to either a NUCLEO-F401RE or a NUCLEO-G431RB development board.

It is also possible to evaluate a system composed of a X-NUCLEO-OUT09A1 stacked on other expansion boards.
