Overview
Ground-fault detection module
"Ground faults in any control circuit must not lead to unintentional
starting or potentially hazardous movements or prevent the
machine from stopping." (IEC 60204-1/VDE 0113-1).
The AS-Interface ground-fault detection module is used to meet
these requirements. Using this module from the SlimLine series,
ground faults in AS-Interface systems can be reliably detected
and reported.
The following ground faults are detected:
•
Ground fault from AS-i "+"
•
Ground fault from AS-i "-"
•
Ground fault from sensors and actuators which are
supplied from the AS-Interface voltage.
Note:
Not suitable for AS-Interface Power24V.
