Description

The STEVAL-IFP040V1 is an industrial digital output expansion board. 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 STEVAL-IFP040V1 can interface with the microcontroller on the STM32 Nucleo

via 5 kV optocouplers driven by the GPIO pins and Arduino® UNO R3 connectors.

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 STEVAL-IFP045V1 stacked on an

STEVAL-IFP040V1 expansion board.

Supplying the STEVAL-IFP045V1 through the main supply rail and the STEVAL-

IFP040V1 through the output of the STEVAL-IFP045V1, 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 STEVAL-

IFP040V1 output can be supplied only when both cascaded systems are properly

working.
