About the SM 1226, F-DI 16x24 V DC
The Siemens 6ES7226-6BA32-0XB0 is a SIMATIC S7-1200 SM 1226 fail-safe digital input module with 16 channels at 24 V DC, configurable as 16 single-channel (1oo1) or 8 dual-channel (1oo2) safety inputs. It reaches Performance Level e per ISO 13849-1 and SIL 3 per IEC 61508 in two-channel mode, with PFH below 1.00E-10 1/h.

Selection Notes
Wiring each input pair a.x/b.x as a single 1oo2 dual-channel circuit reaches the full SIL 3 / PL e rating; leaving channels as independent 1oo1 inputs caps the achievable class at SIL 2 / PL d, so the wiring choice - not a different SKU - decides the safety level on this module. One 16-input module can therefore serve either 16 independent single-channel sensors or 8 redundant safety circuits, versus buying two smaller fail-safe modules for a mixed application.
Applications
E-stop pushbuttons, safety door and guard switches, and light-curtain OSSD outputs wired into an S7-1200 fail-safe CPU via PROFIsafe for machine safety circuits up to PL e / SIL 3.
