Product overview


The X-NUCLEO-OUT01A2 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 ISO8200BQ octal high-side smart power solid state relay, with embedded galvanic isolation, in a digital output module connected to 0.7 A industrial loads.

The X-NUCLEO-OUT01A2 directly interfaces with the microcontroller on the STM32 Nucleo driven by GPIO pins and Arduino® R3 connectors.

The galvanic isolation between the microcontroller and the process stage is guaranteed by the ISO8200BQ.

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-OUT01A2 stacked on other expansion boards.

The board can be configured as the former X-NUCLEO-OUT01A1 by a set of jumpers (open: J13, J14, J15, J16, J17) and switches (close 1-2: SW1, SW28, SW29, SW30, SW31, SW32, SW33, SW35, SW37). In this case, the driving firmware can be only the X-CUBE-OUT1 and the board can be connected to the X-NUCLEO-PLC01A1 to form a powerful industrial PLC with 8 inputs and 16 outputs. Also, wireless communication capabilities can be added with the X-NUCLEO-IDW01M1, which establishes communication on a smart device to manage the PLC remotely. A dedicated ST-PLC app is available for Android™ and iOS™ systems for this purpose.
