Description

The X-NUCLEO-OUT15A1 is an industrial digital output expansion board for STM32

Nucleo. It provides a powerful and flexible environment for the evaluation of the

driving and diagnostic capabilities of the IPS1025HF single high-side, smart power,

solid-state relay in a digital output module connected to 2.5 A industrial loads.

The X-NUCLEO-OUT15A1 interfaces with the microcontroller on the STM32 Nucleo

The expansion board can be connected to either a NUCLEO-F401RE or a NUCLEO-

G431RB development board.

You can also evaluate a system consisting of an X-NUCLEO-OUT05A1 stacked on

an X-NUCLEO-OUT15A1 expansion board.

Supplying the X-NUCLEO-OUT05A1 through the main supply rail and the X-

NUCLEO-OUT15A1 through the output of the X-NUCLEO-OUT05A1, you can

achieve the typical architecture of a single channel digital output for safety systems.

The process stages of the two expansion boards result cascaded. The load

connected to the X-NUCLEO-OUT15A1 output can be supplied only when both

cascaded systems are properly working.
