The primary attributes of this new B11.26 standard are the detailed schematic diagrams, the “Circuit Analysis Tables,” and the detailed annexes for understanding performance levels and category block diagrams as outlined in ISO 13849-1. The intent is to clarify and provide direction for functional safety applications in current and future equipment installations. These detailed generic (non vendor-specific) schematic diagrams are based on actual applications that have been successfully implemented in commerce.
