6ES5 942-7UF11     CPU 942F for S5-115F                                     



If the standard 6ES5 458-7LA11 relay module is used in S5-115F failsafe     

PLCs for testing failsafe inputs, errors may be signalled during the        

background test in isolated cases.                                          


In the case of new installations we recommend to use the 6ES5 453-4UA12     

transistor module for these purposes instead of the relay module.           


In view of the fact that in existing installations a replacement of the     

relay module against a transistor module would be subject to a number of    

restrictions, we are offering a special Z version of the relay module.      


The special version module makes use of selected Reed relays, so that the   

component list of the module does not change. All certificates and appro-   

vals of the standard module thus remain valid.
