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 NUCLEOG431RB
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 STEVALIFP040V1
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 STEVALIFP040V1
output can be supplied only when both cascaded systems are properly working.
