EL2911 - TwinSAFE potential supply terminal with 4
digital fail-safe inputs
The EL2911 is a safe potential supply 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 EL2911 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 up to SILCL3, the safe 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
.
