EJ6910 - TwinSAFE logic module

The TwinSAFE logic EJ module is the link unit between the TwinSAFE input and output modules.

The EJ6910 module meets the requirements of IEC 61508:2010 SIL 3 and DIN EN ISO 13849-1:2016-06
(Cat 4, PL e).

Intended use

WARNING

Caution - Risk of injury!

TwinSAFE EJ modules may only be used for the purposes described below!

The TwinSAFE EJ modules expand the application range of the Beckhoff EtherCAT system by functions that
enable it to be used in the field of machine safety as well. The TwinSAFE EJ modules are designed for
machine safety functions and directly associated to industrial automation tasks. It is therefore approved only
for applications with a defined fail-safe state. This safe state is the wattless state.

The TwinSAFE EJ modules are suitable for operation on an EJ distribution board.

WARNING

System limits

The TÜV-SÜD certificate applies to the TwinSAFE EJ modules, the function blocks avail-
able in it, the documentation and the engineering tool. Approved engineering tools are

TwinCAT 3.1

, 

TwinSAFE Loader

 and 

CODESYS Safety for EtherCAT Safety Module

. Any

deviations from these procedures or tools, particularly externally generated xml files for
TwinSAFE import or externally generated automatic project creation procedures, are not
covered by the certificate.

WARNING

Power supply

An SELV/PELV power supply unit with a voltage limit of U

max

= 36 V

DC

 on the output side

must be used to supply power for the TwinSAFE EJ modules with 24 V

DC

. Failure to ob-

serve this can result in a loss of safety.
