Fail-Safe Digital I/O Modules for SIMATIC S7-1500 Controller

The fail-safe modules expand the range of the S7-1500 system family. They are incorporated seamlessly into the Safety Integrated concept as with ET 200SP/ET 200S/ET 200M/ET 200iSP/ET 200pro and S7-1200. Safety-related communication via PROFIsafe is also supported. The fail-safe modules for digital inputs and outputs (DI and DQ) and analog inputs (AI) are the same size as the 35-mm-wide standard modules. Their functional safety is certified in accordance with IEC 61508. They are designed for safety-related use up to SIL 3 according to IEC 62061 and PL e according to ISO 13849.
