The EL2912 TwinSAFE component is a digital output terminal.

It has two fail-safe outputs with up to 2 A. The outputs are controlled

by a TwinSAFE Logic-capable component via FSoE.

The EL2912 has safety parameters to specifically adapt the functionality

to the respective safety requirements. Thus, for example, a test of the

outputs can be configured with fine granularity in order to be able to

detect cross-circuits among other things and to react appropriately.

In addition, standard outputs can be activated for the EL2912.

As a result, corresponding standard outputs are available in parallel

and internally ANDed with the safe outputs of the EL2912.

The safe output signals, which are controlled by a TwinSAFE Logic, thus

issue the safe release for the standard signals, which can then be

triggered by the non-safety oriented control system independently of the

cycle of the safety controller and FSoE. This allows faster switching times

of the outputs, provided that the safety controller issues the necessary

release for the output.
