STEVAL-SILPLC01, Development Boards & Kits - ARM Safety-ready industrial PLC evaluation board

STEVAL-SILPLC01 is a PLC solution with a 1oo2 architecture, featuring the CLT03-2Q3dual channel digital input and the IPS160HF single channel digital output. The hardware is designed to meet the SIL level. It has been officially assessed by TÜV Italia (TÜV SUD Group) in compliance with SIL 2 / PL d requirements: random failure rates, systematic capability (for the hardware), architectural constraints in accordance with IEC 61508, EN 62061, EN ISO 13849-1, and EN ISO 13849-2 standards. The system is built around the STM32H723VG microcontroller. It is able to manage connectivity, load actuation and system diagnostic check for power management, digital input/output ICs, and temperature monitoring at the same time.
