Industrial safety features

On both boards (STEVAL-SILKTA01 and STEVAL-SILKTB01) have been implemented architectural circuitries,

able to:

•

Cover diagnostic functions to achieve a coverage DC > 90%

•

Implement redundancy on digital input using single channel digital input CLT03-1SC3

•

Implement redundancy on digital output using high-side and low-side architecture (IPS1025H and

IPS4260L respectively)

•

Implement redundancy on the execution of safety functions

•

Implement redundancy on digital output driving signals using dedicated logic gates

•

Implement different power management circuitry to differentiate the power management unit for safety and

non-safety related blocks

The STEVAL-SILKTA01 (main board) as well as the STEVAL-SILKTB01 (actuation board), embeds an isolation

barrier based on STISO621, managing:

•

Serial communication between STM32H743ZG and STM32G431RB

•

Digital input detection

•

Digital output driving

•

Diagnostic signalization for overload and overtemperature.
