S7-1200 PLC SIPLUS SM 1226 fail-safe digital input 6AG1226-6BA32-5XB0

Overview

• Digital inputs as 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 inputs
• Operable exclusively in the central system

Application

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.

Design

• 16 inputs (SIL 2/category 3/PL d), 8 inputs (SIL 3/category 3 or category 4/PL e) or a mixture
