Safety-Ready Industrial PLC Evaluation Board based on STMicroelectronics Solution
The STEVAL-SILPC01 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. 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. The solution integrates DC-DC converters in a buck configuration powered by the L7987L and L7983. The switching converters have been designed to provide 3.5 V on the user side and 6 V on the isolated side. With dedicated post regulation circuits, these voltage levels are stepped down to 3.3 V for the MCU, connectivity, and temperature sensor (available on the isolated side) and 5 V for the signal delta isolator (also available on the isolated side).
