As an alternative to the 3SK1 safety relay, 3RM11/3RM13 Failsafe motor starters can be 
controlled by an F-DO module. In this typical circuit, shutdown is realized by a pm-switching 
F-DO module in 2 channels. 
Up to SILCL 3 in accordance with EN 62061, PL e/Cat. 4 in accordance with 
EN ISO 13849-1 can be achieved. To this end, the controlling outputs must also fulfill 
SILCL3 in accordance with EN 62061/PL e/Cat. 4 in accordance with EN ISO 13849-1.
