The TwinSAFE SC technology (TwinSAFE Single Channel) facilitates

the use of standard signals for safety-related tasks in any networks

or fieldbuses. To do this, EtherCAT I/Os from the areas of analog

input, angle and displacement measurement, or communication

(4 to 20 mA, incremental encoder, IO-Link, etc.) are extended by

the TwinSAFE SC function. The typical signal features and standard

functionalities of the I/O components are retained.

TwinSAFE SC I/Os have a yellow strip at the front of the housing to

distinguish them from standard I/Os.

The TwinSAFE SC technology facilitates communication by means of

a TwinSAFE protocol. These connections can be distinguished from

the usual safe communication by means of Safety over EtherCAT.

The data from the TwinSAFE SC components is transferred by means

of a TwinSAFE protocol to the TwinSAFE Logic, where it can be used

in the context of safety-relevant applications. Detailed examples for

the correct application of the TwinSAFE SC components and the

respective normative classification, which have been confirmed/

calculated by TÜV SÜD, can be found in the TwinSAFE application

manual.
