Siemens 6ES7226-6RA32-0XB0 SIMATIC S7-1200 SM 1226 F-DQ 2x Relay 5A PL e SIL3 Fail-safe PLC I/O Module

The Siemens 6ES7226-6RA32-0XB0 is a SIMATIC S7-1200 fail-safe digital output module, SM 1226 F-DQ 2x relay/5A, rated up to Performance Level e per ISO 13849-1 and SIL 3 per IEC 61508. It supplies two safety relay circuits switching 5 V-30 V DC or 5 V-250 V AC loads, up to 5 A per circuit and 10 A total, and communicates safety data over PROFIsafe.

Selection Notes

The F-DQ prefix marks this as a fail-safe output module for PROFIsafe segments, distinct from a standard SM 1226 relay module — choose it when the application's risk assessment calls for Category 4, PL e or SIL 3 output switching, such as an E-stop chain or guard interlock. Two independent relay circuits, each rated 5 A, cover contactor coils or small motor starters directly without an external safety relay; the 10 A total-circuit limit is the ceiling to check against the combined connected load.

Applications

Used with an S7-1200 F-CPU on machine safety circuits such as emergency-stop chains, safety guard interlocks, and contactor coil switching where PROFIsafe output diagnostics and SIL 3 / PL e rated switching are required.
