X-NUCLEO-OUT12A1

X-NUCLEO-OUT12A1 is an industrial digital output expansion board based on ISO808A for STM32 Nucleo. It provides a powerful and flexible environment for the evaluation of the driving and diagnostic capabilities of the ISO808A octal high-side smart power solid state relay with embedded galvanic isolation and 20MHz SPI control interface, in a digital output module connected to 0.7A industrial loads. The X-NUCLEO-OUT12A1 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 ISO808A. The expansion board can be connected to either a NUCLEO-F401RE or a NUCLEOG431RB development board. It is also possible to evaluate a 16 channel digital output system enabling the daisy chaining feature on two X-NUCLEO-OUT12A1 stacked expansion boards. Suitable for programmable logic controller applications.
