Intended use
Caution - Risk of injury!
TwinSAFE components shall only be used for the purposes described below!
The TwinSAFE EtherCAT Box expands the application range of the Beckhoff system with functions that
enable it to be used for machine safety applications. The TwinSAFE Boxes are designed for machine safety
functions and directly associated industrial automation tasks. They are therefore only approved for
applications with a defined fail-safe state. This safe state is the wattless state. Fail-safety according to the
relevant standards is required.
The TwinSAFE EtherCAT Box allows the connection of:
24 V
sensors such as
DC
• emergency stop push buttons, pull cord switches, position switches, two-hand switches, safety mats,
light curtains, light barriers, laser scanners etc.
• initiators and encoders for speed measurement (frequency) with a signal voltage of 24 V
The fail-safe principle
The basic rule for a safety system such as TwinSAFE is that failure of a part, a system component or the
overall system must never lead to a dangerous condition. The safe state is always the switched off and
wattless state.
Power supply from SELV/PELV power supply unit!
The TwinSAFE components must be supplied with 24 V

Follow the machinery directive!
The TwinSAFE components shall only be used in machines as defined in the machinery directive.
