Siemens SM 1226 – 6ES7226-6RA32-0XB0


  • Relay outputs as a supplement to the integral I/O of the CPUs
  • Integrated into the overall automation for the implementation of safety-related requirements
  • With integrated safety functions
  • Communication with fail-safe CPUs via PROFIsafe mechanisms
  • For flexible adaptation of the controller to the corresponding task
  • For subsequent expansion of the system with additional outputs
  • Operable exclusively in the central system


The fail-safe modules of the PLC  S7 1200 Controller permit the implementation of safety-related application requirements integrated into the overall automation. The safety functions required for fail-safe operation are integrated in the modules. Communication with the fail-safe SIMATIC S7 PLC 1200 CPUs is performed by means of PROFIsafe mechanisms.

The modules can only be operated in central configurations.


  • Two relay outputs (each output switches two circuits)
  • Certified up to SIL 3 (IEC 61508), PL e (ISO 13849)
  • Output current 5 A
  • Rated load voltage 24 V DC or 24 V to 230 V AC
  • Module fault indicator (DIAG; green and red LED)
  • Status indicator for each output (green LED)
  • Fault indicator for each output (red LED)
  • Plain text identification of module type and function class:
    • 2D matrix code (article and serial number)
    • Color coding of the module type DI: White
    • Hardware and firmware version
    • Complete article No.
