Contactors in safety applications
6.11.1
Note
SILCL 3 in accordance with IEC 62061:2005
PL e / Cat. 4 in accordance with EN ISO 13849-1:2015
The contactors with fail
-safe control input are designed in such a way as to allow
implementation of applications up to SILCL
3 in accordance with IEC 62061, PL e / Cat. 4 in
ISO 13849-1.
Safety functional extra-low voltage
Can Cause Death, Serious Injury, or Damage to Property
The fail-safe control input of these contactors is operated with a voltage of 24 V DC. A
power supply unit with safety extra-low voltage (SELV, PELV) must be used.
You can find more detailed information about safety functional extra-low voltage in the data
sheets of the power supplies to be used.
