The IB IL 24 SAFE 1-PAC safety terminal is designed for use within the 24 V area of an
Inline station. It can act as an emergency stop safety relay, a safety door monitor or
secondary switchgear for control strips and safety mats.
The safety terminal can be used to achieve safety functions with requirements up to
category 4 according to standard EN 954-1.
Figure 4-11
The safety terminal can be used to create a safety-related segment circuit.
The structure of the safety-related segment circuit in the Inline system is such that
actuators/controlled devices, which are connected to output terminals, can be switched
separately via the bus system and can be switched off safely on a safety demand to the
pre-connected safety terminal.
The safety-related segment circuit starts at a safety terminal and finishes at the last terminal
before another power supply unit or at the end of the station. Only Inline terminals that are
specifically designed for the safety-related segment circuit may be used. They are listed in
the "Safety-related segment circuit" application note, AH EN IL SAFE.
The IB IL 400 SAFE 2 terminal is available as a contact extension for this safety terminal. It
is used for the safe disconnection of the 400 V three-phase supply for the subsequent
power-level terminals.
