The Siemens Safety System Circuit Board (Sicherheitssystem A30) is an industrial-grade printed circuit board engineered for critical safety applications and automation environments. Built on a robust green PCB substrate, this module is populated with high-quality integrated circuits and electronic components to ensure reliable operation. It features multiple green screw terminal blocks, specifically designed for secure and organized wiring, with 10-pin configurations for X1 and X2, and 12-pin configurations for X3 through X6. For added component protection and operational safety, the board includes an integrated fuse holder (designated as F1) equipped with a 3.15A rated fuse.
