The power supply accessory is characterized by:
•
Voltage supply to the safe sensor cascade and connection of additional power
supply units (
see "Connection facilities", page 28
)
•
electrical isolation in individual sections
•
shutdown of the safe sensor cascade or the section in case of overload
Depending on the number of Flexi Loop nodes, the length of the cables, and the power
consumption of the connected sensors or actuators, a voltage supply from a single
power supply unit might not be sufficient. Should this be the case, additional power
supply units can be connected with the power supply accessory.

Principle of operation
3.2.1
Operating principle of Flexi Soft
The Flexi Soft I/O modules provide the interface to the Flexi Soft safety controller.
Safe cut-off path
The safety information on the switches and sensors connected is combined and trans‐
mitted quickly and safely to the Flexi Soft.
