Simple muting – all needed signals in one single module

February 18, 2018


The new AS-i Safety I/O Modules from Bihl+Wiedemann allow you to connect all the signals needed for muting to just one module. Profit from a space-saving solution with many in- and outputs. The module is also simple and highly flexible to configure.


Another advantage: If you have already been combining AS-i with “non-AS-i“ muting switching devices, you will be able to use our new modules to convert all your muting to a uniform technology. This saves costs in commissioning, maintenance and service.

•  Up to 8 two-channel safe inputs (SIL3, PLe)

•  Up to 2 release circuits (2 × fast redundant electronic safety outputs)

•  Connection of periphery using 8 × M12 socket (5-pin)
