10.2 Safe shutoff for products with IO-Link
INFORMATION
For safe shutoff for IO-Link products, two contactors are switched in series with one auxiliary contact each. Here,
the auxiliary contacts monitor the status of the contactors. If one contactor does not switch, the second contactor
ensures safety. The malfunction can still be detected using the contacts.
The following example corresponds to control category 3 and the PLd can be reached in any case. PLe in control
category 4 can be reached only if S24V is also shut off with two channels and with error monitoring, similar to the example
above. The product cannot carry out a hazardous movement.

Product with IO-Link without external STO cable
NOTICE
Without an externally fed power supply, the motor of the product cannot carry out an active movement and thus
cannot carry out a hazardous movement.
There is no galvanic isolation between the two voltage supplies (signal and power). There is a low-voltage
connection via ground (GND).
Because of the self-locking mechanism, the product remains in the last approached position, even if no power is
supplied.
