SIMATIC S7-1200 – Relay Output SM 1226 – Siemens Fail-Safe I/O Modules
$ 279.84
SKU: 6ES7226-6RA32-0XB0
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.
