SIMATIC S7-1200 – Digital Input SM 1226 – Siemens Fail-Safe I/O Modules

 184.21

SKU: 6ES7226-6BA32-0XB0

The fail-safe modules of the SIMATIC 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 CPUs is performed by means of PROFIsafe mechanisms. The modules can only be operated in central configurations
