4.1 EL2911 and EL2911-2200
The EL2911 is a safe potential feed terminal for the power contacts for a downstream potential group. In
addition, it has 4 fail-safe inputs for sensors with potential-free contacts for 24V
DC
.
The EP2911 meets the requirements of IEC61508:2010SIL3 and ENISO13849-1:2015(Cat4, PLe). The
safe inputs of the EL2911 meet the requirements of EN62061:2005/A2:2015 to SILCL3, the safer output up
to SILCL2.
The TwinSAFE Terminal has the usual design of a 24 mm EtherCAT Terminal. It has no power contacts on
the left side and therefore forms the start of a new potential group.
The safe inputs and the safe output are supplied from U
P
.

The EL2911 has an integrated safety control that can be used for user-specific applications directly
on the component. The variant EL2911-2200 does not have this functionality and represents a pure
I/O component.
