The EL2911 TwinSAFE component is a potential supply terminal

and enables the setup of TwinSAFE groups with a safe power

supply (24 V DC, up to 10 A). If the TwinSAFE terminal detects

an error, it switches to the safe state (fail-safe).

Safe potential groups can be created within a terminal segment

using the EL2911. Thus, interference-free standard terminals

can be safely switched off and integrated into the safety application.

In addition, the EL2911 has four safe inputs.

The safety-relevant data are exchanged via FSoE with a TwinSAFE

Logic-capable component.

The safety parameters are not stored directly on the component,

but are transmitted to the input terminal via a TwinSAFE Logic

capable component when the safety application is started.

This simplifies service procedures, because in this case the component

can simply be replaced. The safety-relevant parameters are transferred

to the new component when the safety application is restarted.
