Safety-related shutdown
Note
The digital output module DQ 4x24VDC/2A HF supports safety-related shutdown in
connection with a fail-safe power module F-PM-E 24VDC/8A PPM ST:
• SIL according to IEC 61508: 2
• Highest attainable safety class in safety mode, performance level according to
EN ISO 13849-1: d
Residual current for signal state "0"
Note
Residual current for signal state "0"
Due to the Diagnostics: Wire break function, there is a low level of residual current in the "0"
signal state at the output, which may cause the display diodes to flicker.
This residual current does not depend on the setting for the Diagnostics: Wire break
parameter.
